These photos and instructions were put together by Stelleria from Fern and Faerie – thank you Stell!
For this project, you will want to use a ball-point or universal sewing machine needle, so you don’t punch holes & cause runs in your fabric. A size 80 or 90 will do the trick.
Cut 4 pieces per diaper. For a standard-size 4×8x4 prefold I cut mine 18″x18″. Go by the desired finished length, and use that measurement for the dimensions of your square.
Take 2 layers, and fold them in half, right sides out. Repeat with the other 2 layers. In the photo, the folded edges are both in the center.
Overlap the two folded stacks so the overlapped part is the same width as the sides. Pin along the folded edges, and then topstitch close to the folds on both sides.
Cut a piece of Snappi-able fabric the same size as your diaper. Layer this over the diaper, and pin. Loose weaves, terry-cloth, the wrong side of sherpa, or pique knit are usually Snappi-able.
Serge around the edges, rounding off the corners. Alternately, you can straight-stitch around the edge, then zigzag to overcast the edges.
If you don’t want to back the whole diaper with Snappi-able fabric, you can conserve fabric by using strips. I cut mine 3.5″ wide, serged the edges, and sewed them in place using the illustrated steps. This diaper was made using a waffle-knit shirt for the Snappi-able fabric.
Pin the center strip in place, then topstitch.
Lay top strip out in flipped-down position. Pin & sew the seam.

Flip up, pin & trim.
Serge to finish.

With slight variations, you can make your prefold stuffable. This is good for customizing absorbency, conserving fabric, and shortening the drying time.

Make a 2×4x2 prefold (only two squares are used, rather than 4). Serge across the top only.
Cut your backing piece from a Snappi-able fabric. Serge across the top of that.
Layer your prefold and backing pieces, with the serged edges at the top. Pin together. Serge around the edges, beginning 1″ to the outside of the center overlap and ending in the same place on the other side of the overlap, leaving an opening about 6" wide along the top.
Use the sleeves of your Snappi-able shirt, or another suitable garment to cut your soaker pads. I made mine 2-layer, 4″x15″. Serge around the edges.
Sometimes you may find a shirt with something you’d like to show, but the fabric isn’t Snappi-able on the right side. In this case, you can sew patches of Snappi-able fabric at the top corners and the center bottom before layering & serging.

What does “zigzag to overcast the edges” and “snappi-able fabric” mean?
December 30th, 2008 at 4:59 pm
Jessica says:
If you don’t have a serger, you can use your sewing machine to lock the raw edges of the fabric together. Using a wide zig-zag stitch, stitch with half the “zig” on the fabric and half of it just off the edge. It’s not as tidy looking as a serged edge, but it does the trick.
Snappi diaper fasteners are easy ways to close cloth diapers shut without using pins. They have little “hooks” that grab the fabric, and they don’t grab well on all fabrics. Fabrics Snappis work well with are: birdseye, french terry, stretch terry, and regular loop terry. They will grab onto jersey knit fabric (t-shirt material) but can tear holes over time. They will NOT grab onto flannel.
You can see Snappis here if you aren’t familiar with them, most diaper stores carry them: http://www.snappibaby.com/
