Double Body Layers - The outside is a waterproof fabric. We recommend: Polyester, Polyurethane Laminate ‘PUL’. The inner layers are referred to as ‘absorbent body layers’ in this instruction guide. We recommend a thin, soft absorbent fabric such as: 100% cotton birdseye fabric. Other fabrics such as: sherpas, cotton French terry, hemp French terry, hemp fleece or woven terry towelling may be used but keep in mind these fabrics are thicker and can result in a bulkier AIO. For the soaker pad,  we recommend using 100% cotton birdseye fabric or 100% cotton diaper flannel. If you use thicker, bulkier fabrics for the soaker pad, only use 3 to 4 layers. Super Doublers are made of 1 layer of diaper flannel and 2 layers of birdeye.


Thread: high quality 100 % polyester thread

Elastic: ¼”polybraid or cotton swimsuit elastic. ½ yard for Newborn, Small. 2/3 yard for Medium, Large.

Hook and Loop: Aplix® or Touchtape® brand hook and loop sew on tape. See below.

Needles: 14/90 universal needles.

4 inches of hook,                12 inches of loop. 1”wide

4 inches of hook,                     15 inches of loop. 1.5” wide

4 inches of 1.5” wide hook, 15 inches of 2” wide loop



Single Diaper: 2 1/8 yards 36” wide birdseye for two full body layers, 8 layers of the soaker pad and 2 doubler pieces. ¼ yard of diaper flannel for one layer in the super doubler – or use a scrap 5/8 yard 60” wide waterproof fabric for one outer layer. If you use 60” wide you’ll have enough waterproof fabric for a second outer layer for your next diaper.

One dozen diapers – Making many diapers at a time is the best way to maximize your fabric width and use fabric economically. 24 yards of 36” wide birdseye fabric will yield 12 diapers, their soakers and 2 layer super doublers. Add 2 yards of diaper flannel for the third layer in the super doublers. 3/5 yard of 60” PUL will yield 12 outer layers.
