The pattern I used is the Rocket Bottoms One Size Diaper. The pattern includes fold over rise snaps to make it one size. I added a front snap rise adjustment instead. I like both methods, but I use less snaps for the front placing rise adjustment. I used my own contour soaker pattern, but any design is great. Here is how to make the diaper.
1. For the diaper layers use woven cotton print for the outer layer, polyester fleece for the hidden layer and hemp/organic cotton fleece for the inside layer. Mark the placement of the snaps on the outer layer and add the front sockets prior to assembly to make them hidden. Mark the placement of the elastic to the outer layer. This is optional but you can add an additional layer of polyester fleece in the wet zone and sew it to the inside hemp fleece layer. Mark and add the snap in soaker sockets to the hemp fleece layer.
2. Cut the layers for the snap in soaker. Use 6 layers of hemp fleece and one layer of cotton velour for the top. Add the stud snaps for the snap in soaker to the bottom two layers. Cut two 6.5 inch pieces and one 5 inch piece of 3/8 inch braided elastic for the legs and back.
3. Sew the outer woven fabric with the polyester fleece and the hemp fleece inner fabric together with wrong side facing outwards. Leave a small gap at the top of the diaper to turn. Sew on the ends only of the elastic to the markings on the legs and back.
4. Turn the diaper right side out. Stitch around the entire diaper closing the open edge and making sure to not catch the leg and back elastic. For the legs and back, stitch a half inch casing making sure to not catch the elastic in the sewing. Add the wing snaps to the outside of the diaper.
5. To make the petal soaker, first serge the three bottom layers together with the snaps on the bottom. Serge the top three layers together with the cotton velour on top. Sew the two petal pieces together at the top corners. Diaper is all done!
