This was a great pattern. I love the finished project. I used a yarn-dyed houndstooth woven cotton. It's medium weight and isn't super drapey. I think it worked very well in the end.
I had to alter the shoulders very slightly, because the pattern was written for a more delicate person than myself. I just decreased the seam allowance at the neck from 1/2" to 1/4" starting to taper about 4" from the neckline. It worked well enough. I think my shoulders may just be more suited to a set in sleeve.
