I do not see anything wrong with her blocks. I thought that using colors you like rather than colors someone else dictates was the fun part of quilting.

looks perfect from here. Very nice.

The centers aren't mismatched...It's a unique design that your GG invented. Very nice.

No quilt police here! I think it looks very nice.

I have a quilt top my aunt made and she did not want any more. She gave it to me and no, it is not perfect but she made it and that is what is important to me.
