With the leftover fabric from this shirt, I figured I try making a Pillowcase dress for Anna using the free tutorial/pattern by Habitual. It was easy to make, but I have to admit to not following any of the directions, so maybe that's not a fair assessment of the pattern.
For the boy
It's reverse applique Alabama Chanin style (thread ends on the outside). Once I finished it I thought I should have done a tutorial, but here's another one if you really are interested. I TAPE my fabric to the inside with masking tape instead of pinning though.
