I'm giving up on my 12" compass star for now. I ripped off all the secondary points, re cut them very carefully and started putting them back on, and having problems. I think I did not get my inner seams wide enough so the center is too big for the outer points. I know I sew an extra skimpy 1/4", and I was being super extra careful to be exact, which would result in an even skimpy 1/4" seam.
I've been doing a lot of paper piecing recently, I think it's time to do something that does not require so much attention to detail. I think I'll go do some strip piecing until my eyes get uncrossed!
