I've finished my first pillowcase 'dress' (actually, its tunic length on the Newbie, who's a month old today!). I love the finished product:
Here's the details:
Pattern: View D of Simplicity 4243
Added sleeves as per Views A and B, and added a button placket with two buttons at the back, rather than the recommended zipper
Pillowslip (including lace from base), buttons and bias binding from the stash
Read the instructions rather than charging ahead! The construction process would have been a lot easier if I had have inserted the sleeves before sewing the side seams (as detailed in the instructions) rather than after. I found the bias facing for the neck difficult to use due to the reasonably tight curve on the neckline - will try a different approach next time I think.
After more inspiration? I'm linking up here, here and here.
