pbadder, not sure but I think they are suppose to be 9 1/2" square. I made 1 trial block and did exactly 1/4" seams, being very careful to match those points and barely had any to trim. Did you oversize your starting squares or sew 1/8" seams? That's the only thing I can think of to why they are 1/2" larger.
Pattia, it's all in the way it's cut this time, totally different from what we've been doing, try a practice one maybe. I did just because I wanted to make sure they were accurate. Takes a little pinning this time to get everything to match up....at least it did for me.
