Well I liked the Mama Bird pattern so much, I decided to try it again - this time all in knit fabrics, and with a sewn-in soaker, rather than pocket-style. If I get ambitious (not tonight - I don't sew well past midnight! :), I'll make a lay-in doubler for extra absorbency.
This is my favourite diaper I've made so far - I LOVE it out of knit. The outer layer is a soft stretch terry, and the inner layers and doublers are made out of - you guessed it - more t-shirts.
