I made this last week but didn't post it. I used the pattern for my top and just cut a slit down the front. I was looking for an easy, quick, short sleeve jacket pattern and could find one. So I just made this.
Fabric was just a inexpensive one from Walmart to test on something. So this worked. It's actually very light fabric and a bit slick. Used my roller foot for the hem.
The sleeve is not that stiff, I just held it out to show the pattern.
