Take this question over to the "Crafts" section of the Nest, lots of ladies over there have made these dresses! Hopefully that gets you more bites. GL!
I just made a couple yesterday. It wasn't out of a pillowcase, though. I used 1 yard of fabric and made 2 size 3-6 month dresses with a little fabric leftover.
