If your center was the correct measurement then it should match perfectly Pam. I very seldom sew a scant 1/4"...if a pattern calls for it I adjust so I have a true 1/4" seam. Think I've seen to many other quilts that those scant 1/4"s were less than that and the minute you wash them those seams start to shred. On all the rounds that I have given I have sewn them the full 1/4" seam, I'm pretty sure Linda has too because she is really trying to get better at those, she got a new pressure foot and all. 11 seams can make a bunch of difference.
