Making a DIY top quilt is one of the most rewarding gear projects a backpacker or hammock camper can take on. You choose the exact width, length, warmth and color, and you learn how your sleep system actually works. A top quilt is also one of the simplest pieces of insulation to build: there's no hood, no full-length zipper and very little shaping.

This pillar guide gives you the full picture: the two main routes (synthetic and down), how to size your quilt, yardage and fill math, a complete materials list, and the build sequence. For detailed walk-throughs, see our dedicated guides to a DIY synthetic quilt and a DIY down quilt. Hammock campers can apply the same skills to a DIY underquilt.

Should you make your own top quilt?

DIY isn't for everyone. Cottage makers produce excellent quilts at fair prices, and a first DIY quilt will have some wobbly seams. But DIY makes a lot of sense if:

• You want a size or feature nobody sells, like an extra-wide quilt for a hammock or an unusual length.
• You're on a tight budget and willing to trade time for money, especially with synthetic insulation.
• You enjoy sewing or want to learn, and you plan to make more gear later.
• You want to understand gear construction to make better buying decisions.

If you mostly want the warmest, lightest quilt for the money with no hassle, compare our best top quilts and custom vs stock quilts first. A pre-cut DIY quilt kit is a middle path that removes most of the measuring and cutting.

Synthetic vs down: choosing your DIY route

The single biggest decision is insulation. It changes the skills, tools, time and cost of the project.

Weights are rough estimates for a 54 x 78 inch tapered quilt and depend heavily on fabric choice. Our full comparison of down vs synthetic quilts covers performance differences in the field.

Our recommendation: make a synthetic quilt first. It teaches you how to handle slippery nylon and assemble a quilt shell, and the finished quilt is genuinely useful for summer, hammock camping, bikepacking and wet climates. Then build a down quilt once you know your preferred dimensions.

Sizing your DIY quilt

Commercial quilts come in a few standard widths and lengths. DIY lets you pick exactly what you need. The key measurements:

• Length: your height plus enough to cover your head or reach your chin with the footbox closed. For a top quilt that stops at the neck, a common rule is to make the finished length roughly equal to your height, or a few inches more if you like to pull it over your head.
• Shoulder width: the widest part, roughly where your shoulders sit. 50–54 inches suits most ground sleepers on a 20-inch pad; 54–58 inches is better for side sleepers, broad shoulders and hammocks.
• Foot width: 38–42 inches at the footbox opening is common before closing.
• Taper start: keep full width for the top 20–30 inches, then taper toward the foot.

Measure a blanket or sleeping bag you already like, or use our quilt size calculator. The deep dive is in quilt width and length sizing.

Yardage math for a standard top quilt

Let's work through the most common build: a quilt that finishes around 54 x 78 inches for someone up to about six feet tall.

Shell fabric

1. Cut size per layer: 54" + 1" seam allowance + 1" loft allowance = 56" wide. 78" + 1" + 1" = 80" long.
2. Fabric width: most ultralight nylon is sold around 58–62 inches wide, so a 56-inch panel fits across the width with a little to spare. Confirm the usable width with your supplier.
3. Length per layer: 80 inches is about 2.22 yards. Round to 2.25 yards.
4. Two layers: 2.25 x 2 = 4.5 yards. Buy 5 yards to allow for squaring the ends and mistakes.

If you want a different color inside and out, buy 2.5 yards of each.

Synthetic insulation

Climashield Apex is commonly sold by the yard in widths around 60 inches; check your supplier's actual width. For one layer you need the same 80-inch length: about 2.25 yards. If you stack two layers of Apex to reach a warmer rating, double it.

Down fill (estimate)

Down quantity depends on target loft, quilt area and fill power. A rough method:

1. Area: average width x length. For a quilt tapering from 54" to 40", the average is about 47". 47 x 78 = 3,666 square inches.
2. Target loft: about 2.5 inches single-layer for a quilt aimed near 20°F.
3. Volume: 3,666 x 2.5 = 9,165 cubic inches.
4. Divide by fill power: 9,165 / 850 = about 10.8 oz.
5. Add overfill: down in a real quilt rarely reaches its lab fill power, so DIYers commonly add 15–30%. 10.8 x 1.2 = about 13 oz.

That lines up with many commercial 20°F quilts using 850 fill power down. The DIY down quilt guide shows how to split this across baffle chambers. Background reading: down fill power explained and fill weight and overfill.

Choosing insulation weight and warmth

Climashield Apex is sold in weights measured in ounces per square yard. DIY suppliers and the hammock community commonly pair them with rough temperature ranges like these. Treat them as starting points, not ratings:

Warmth also depends heavily on your pad or underquilt. On the ground, see sleeping pad R-value for quilts; in a hammock, see the hammock insulation guide. Most commercial quilt ratings are not lab-tested either, as we explain in top quilt temperature ratings.

Shell fabric choices

Ultralight nylon ripstop is the standard. Lighter fabric saves weight; heavier fabric resists snags and is easier to sew.

• Around 7D–10D nylon (roughly 0.5–0.8 oz/yd²): very light and soft, slippery to sew, and more delicate.
• Around 15D–20D nylon (roughly 0.9–1.2 oz/yd²): a good balance for first builds and outer shells.
• Heavier 30D–40D: durable but noticeably heavier; useful for hammock underquilts or kids' quilts.

For down quilts, choose a fabric marketed as downproof. A DWR finish on the outer shell helps shed condensation. Read quilt shell fabrics and our top quilt fabric designers page for options and patterns.

Complete materials list

Fabric and insulation

• About 5 yards of ultralight nylon ripstop for both shells. Specialist supplier Ripstop by the Roll carries a wide range of quilt fabrics; general ripstop nylon by the yard is also available.
• Synthetic route: about 2.25 yards of Climashield Apex in your chosen weight.
• Down route: roughly 10–15 oz of quality down, plus noseeum mesh for baffles (about 1–1.5 yards, depending on baffle count and height).

Notions and hardware

• About 2–3 yards of 5/8" or 3/4" grosgrain ribbon for drawcord channels and attachment loops.
• About 3 yards of thin cord (around 2 mm) for the neck and footbox drawcords.
• Two small cord locks.
• Optional snaps or a short zipper to close the footbox, and loops for pad straps.
• Optional line-lock buckles for adjustable pad straps; see DIY quilt pad straps.

Tools

• A home sewing machine with a reliable straight stitch.
• Microtex 70/10 needles: sharp, fine points that pierce tight-weave nylon cleanly. Bring spares.
• Polyester thread, a fine all-purpose weight. Avoid cotton, which absorbs water and weakens.
• Quilting clips instead of pins; pins leave permanent holes in nylon and can create down leaks.
• A rotary cutter and cutting mat for straight, clean cuts.
• A long straightedge, measuring tape and fabric marker or chalk.
• A large clean floor or table for layout.
• For down: a digital scale that reads to 0.1 g, bags or cups for portioning, and a room without drafts.

Step-by-step: how to build a DIY top quilt

This overview applies to both routes. The synthetic route is shown in full; down-specific steps are noted and covered in depth in the down quilt guide.

1. Make a pattern. On kraft paper or directly on fabric, draw a rectangle at your cut size (for example 56 x 80 inches). Mark the shoulder line about 24 inches from the head end, then draw straight taper lines from the shoulder corners to the foot width. Fold in half lengthwise to ensure both sides match.
2. Cut the shells. Lay out fabric on a flat surface without stretching it. Cut the outer and inner shells with a rotary cutter. Mark the head and foot ends.
3. Cut the insulation (synthetic). Lay the Apex flat and cut it to the same pattern. Apex is easy to cut with scissors or a rotary cutter.
4. Stack the layers. For the "pillowcase" method: lay the Apex flat, place one shell on top right side up, then the second shell on top right side down, so the two shells' good sides face each other. Clip all edges every few inches.
5. Sew the perimeter. Stitch around the edges with a 1/2 inch seam allowance and a stitch length around 2.5–3 mm, leaving an opening of 12–18 inches along the head end for turning.
6. Trim. Trim the Apex close to the stitching to reduce bulk, and clip the fabric corners at an angle without cutting the stitches.
7. Turn it right side out. Reach through the opening between the two shell layers (not under the Apex) and pull the quilt through. The Apex now sits between the two shells. Push the corners out gently.
8. Close and topstitch. Fold the opening's raw edges inward and clip them. Topstitch around the entire perimeter about 1/4 inch from the edge; this closes the opening and keeps the insulation from rolling.
9. Add drawcord channels. Sew a strip of grosgrain or folded fabric across the head end and the foot end to form channels. Thread cord through with a safety pin and add cord locks.
10. Form the footbox. Fold the quilt in half lengthwise at the foot and sew the bottom 15–20 inches of the edges together to make a closed footbox, or add snaps or a zipper there if you want the quilt to open flat. The foot drawcord closes the bottom. See open vs sewn footbox.
11. Add pad attachment loops. Sew small grosgrain loops along both long edges, typically at the shoulder and hip, with a box stitch for strength.
12. Optional quilting. Apex is a stable sheet and many DIYers make quilts without interior quilting lines. Some add a few short tack points to keep layers aligned on wide quilts.

Down route differences: instead of a single insulation sheet, you sew mesh baffle strips between the inner and outer shells to create chambers, close three sides of each chamber, weigh and insert down chamber by chamber, then close the last edge. It's more time and more mess, but the result is lighter and more compressible.

Sewing tips for slippery ultralight nylon

• Use clips, not pins. Clips hold layers without puncturing them.
• Support the weight. Let the quilt rest on a table behind and to the left of the machine so its weight doesn't drag the seam.
• Go slow. Ultralight fabric shifts. Sew at moderate speed and guide, don't pull.
• Use a walking foot if you have one. It feeds both layers evenly and is especially helpful with lofty insulation.
• Change needles often. A slightly dull needle causes skipped stitches and pulls on thin nylon.
• Hot-cut or seal edges if fraying is a problem on a particular fabric, though most ripstop holds well with clean rotary cuts.

Cost and weight expectations

Material prices change frequently, so check suppliers before you plan. In general terms:

• Synthetic quilt: materials typically land in the $ price tier (under $150), often well under a comparable synthetic cottage quilt.
• Down quilt: high-quality down is the biggest expense. Materials often reach the $$ tier ($150–300), which can approach the cost of a budget commercial down quilt. The savings come from customization more than price.

Expect your first quilt to weigh a little more than a commercial equivalent, mainly from extra seam allowances and heavier fabric choices. See the quilt weight guide for benchmarks.

Customizations worth considering

• Draft collar or snap-together neck: great for cold nights; see the draft collar guide.
• Extra width for hammocks: a wider quilt seals better as you shift on a diagonal.
• Wearable features: a head-hole slit with a snap or poncho-style opening can turn a quilt into camp wear. See wearable quilts.
• Two-piece system: a light synthetic quilt plus a down quilt layered together for winter. See quilt layering systems.
• Hammock-specific top quilt: some DIYers skip pad loops and add snaps to close the quilt around them. See the hammock top quilt guide.

Common DIY mistakes

• Making it too narrow. Drafts are the number-one complaint with quilts. Add width if in doubt.
• Forgetting loft allowance. A quilt that measured right flat ends up short once lofted.
• Using pins. Holes in downproof fabric become leak points.
• Cotton thread. It absorbs moisture and is weaker than polyester.
• Rushing the cut. A wonky pattern makes every later step harder. Measure twice.
• Underfilling down. Chambers that aren't full let down shift, creating cold spots. See fixing down shifting.

Caring for your DIY quilt

A homemade quilt needs the same care as a commercial one. Wash a synthetic quilt with a technical cleaner and dry on low or no heat, as in washing synthetic quilts. Wash a down quilt with down-specific soap and dry it thoroughly, per how to wash a down quilt. Store either type uncompressed, following how to store a quilt.
