5 Best Fabrics for Making Cloth Diapers

Creating handmade cloth diapers isn’t just a thoughtful project for new parents or a meaningful baby gift—it’s a craft that demands precision, material knowledge, and an understanding of how fabrics behave under real-world conditions. At Pura Fabric, we’ve worked closely with sewists, from hobbyists to small-batch designers, who’ve shared their triumphs and frustrations in constructing functional, long-lasting diapers. The right fabric choice doesn’t just affect comfort; it determines absorbency, durability, and even how well a diaper holds up after 200+ washes. Based on years of customer feedback, lab testing, and hands-on sewing experience, here are the five best fabrics for cloth diapers—each with its own strengths, quirks, and ideal use cases.

Bamboo Fleece

Why It Works—and When It Doesn’t

Bamboo fleece is a favorite among experienced cloth diaper makers, and for good reason: it’s plush, breathable, and naturally antimicrobial. But beyond the marketing claims, its real advantage lies in its fiber structure. Bamboo viscose fibers swell when wet, closing gaps in the weave and creating a temporary moisture barrier—ideal for preventing leaks during daytime use.

I once worked with a designer who used bamboo fleece for a custom diaper liner, only to find it sagging after a few washes. The issue? She hadn’t pre-washed the fabric. Bamboo fleece can shrink up to 10% on the first wash, especially if it’s not tightly knit. Once she adjusted her pattern to account for shrinkage and used a wool-setting on her dryer (low heat, short cycle), the fit stabilized completely.

Another common mistake: pairing it with non-breathable waterproof layers. One customer layered bamboo fleece directly under PUL without a moisture-wicking inner layer, leading to trapped dampness and chafing. The fix? Insert a thin layer of bamboo velour between the fleece and PUL to move moisture away from the skin.

At Pura Fabric, our bamboo fleece is pre-shrunk during finishing, reducing this risk significantly. It’s also brushed on one side for loft without compromising drape—making it easier to sew through than bulkier cotton fleeces. It’s warm, yes, but not overheating, thanks to bamboo’s natural thermoregulation. For winter babies or sensitive newborns, it’s unmatched.

Bamboo Terry

Managing Absorbency Without Bulk

Bamboo terry is the workhorse of cloth diapering. It’s not just absorbent—its capillary action pulls liquid deep into the core, faster than cotton. In lab tests, our bamboo terry absorbed 30% more liquid in the first 30 seconds compared to standard cotton terry. That speed matters when you’re dealing with a heavy wetter.

But high absorbency comes with trade-offs. I’ve seen sewists struggle with tunneling on the edges when topstitching—those puckered ridges that form when the terry compresses under tension. The root cause? Using a standard needle and thread. Terry’s looped pile compresses unevenly, especially with polyester thread, which doesn’t stretch. Switch to a size 90/14 jersey needle and a woolly nylon thread in the bobbin, and the stitches give just enough to prevent tunneling.

Another issue: slow drying. Bamboo terry retains moisture longer than cotton, so diapers with thick inserts can stay damp in the center after a standard dryer cycle. A customer once complained of mildew smell—turned out she was folding wet inserts directly into a diaper pail. The solution? Tumble dry inserts on medium for 45 minutes, then air-fluff for another 20. Or better yet, use a moisture alarm to test dryness before storage.

At Pura Fabric, we offer bamboo terry in a mid-weight (380 GSM), which balances absorbency and dry time. It’s also dyed with OEKO-TEX certified pigments, so there’s no color bleed—even after repeated washing. For overnight diapers or all-in-one designs, it’s our top pick.

Bamboo Velour

The Hidden Challenges of Luxury Texture

Bamboo velour feels like a cloud—soft, slightly slick on the surface, with a dense, brushed pile. It’s a go-to for stay-dry inner linings because it wicks moisture away from the skin, keeping baby comfortable. But that same smoothness makes it a nightmare to sew if you’re not prepared.

I once watched a client struggle with skipped stitches when sewing velour to PUL. The problem? The velour’s surface slid against the presser foot, throwing off alignment. She switched to a walking foot, reduced presser foot pressure, and used a 75/11 microtex needle—immediate improvement. The microtex needle pierces cleanly without dragging, and the walking foot prevents layer shift.

Another issue: lint. Velour sheds. A lot. During a workshop, we had a serger jam mid-project because lint clogged the tension discs. Now, we recommend cleaning the machine after every two seams when working with velour. A quick blast with compressed air and a soft brush makes a huge difference.

And don’t underestimate the aesthetic value. One designer used charcoal bamboo velour with gold-thread edging for a luxury gift line. The slight sheen gave it a boutique look, and parents consistently reported fewer rashes—likely due to the smooth, non-abrasive surface. At Pura Fabric, we stock velour in rich, saturated colors that don’t fade, even after months of washing.

Organic Cotton Fleece

When You Need a Cotton Alternative

Not every baby tolerates bamboo. Some parents report irritation—though rare—possibly due to sensitivities in the viscose processing. For these cases, organic cotton fleece is a reliable alternative. It’s not as absorbent as bamboo, but it’s breathable, hypoallergenic, and holds up remarkably well over time.

One challenge with cotton fleece is fraying. I once saw a diaper with raw-edged fleece inserts that unraveled after five washes. The fix? Encase the edges in a serged or zigzagged seam, or bind them with cotton lycra. Another option: use a 3-thread overlock with woolly nylon in the looper—adds stretch and durability.

Cotton fleece also pills more than bamboo, especially with friction from diaper covers. To minimize this, avoid washing with rough fabrics like denim or towels. One customer washed her cotton fleece diapers with microfiber inserts—big mistake. The microfiber abraded the surface, causing pilling within weeks. Now, she separates loads by fabric type, and the diapers look new after six months.

Pura Fabric’s organic cotton fleece is GOTS-certified, meaning it’s grown without synthetic pesticides and processed without harmful chemicals. It’s slightly heavier than bamboo fleece, which some parents prefer for added warmth. And because it’s less elastic, it’s easier to cut and align with patterns—ideal for beginners.

Organic Cotton Velour

Balancing Softness and Structure

Organic cotton velour is often overlooked in favor of bamboo, but it has unique advantages. It’s less prone to static, doesn’t feel clammy when damp, and maintains its softness longer than bamboo velour after repeated washing. The fiber is shorter and denser, giving it a more structured drape—perfect for diapers that need to hold shape.

But cotton velour can be tricky to layer. I once worked with a sewist who fused it directly to PUL with iron-on adhesive. The result? Stiff, crackly seams that irritated the baby’s legs. The solution? Skip the adhesive. Instead, use a narrow zigzag or stretch stitch to attach it, allowing the layers to move independently.

Another common issue: misaligned nap. Velour has a directional pile, and if you cut pieces going opposite directions, the color looks different under light. One batch of diapers came back with alternating light and dark panels—turns out, the sewist hadn’t laid all pattern pieces in the same direction. Now, we always mark the “up” arrow on our cutting templates at Pura Fabric.

Parents who prioritize chemical-free materials love this fabric. It’s especially popular in Europe, where demand for non-viscose, plant-based textiles is high. And with our range of muted and vibrant colors, it’s a favorite for gender-neutral and heirloom designs.

Final Thought

Choosing the right fabric for cloth diapers isn’t just about softness or absorbency—it’s about understanding how materials behave over time, under stress, and in real-life conditions. Whether you’re sewing for your own baby or building a small brand, the details matter: needle type, washing routine, layer compatibility, and even how you store your fabric before cutting. At Pura Fabric, we don’t just sell textiles—we support the craft behind them.
