The blocks are 12 1/2". The pictures weren't clear. I take horrible pictures. I use my cell phone. But thank you for saying nice things about my quilt. Now, I have to bind it. And I won't say "hate", but binding is something I would rather never ever do. I actually pay people to do my binding. I'm so bad. My LQS owner bound my last quilt. She machine binded it with a flower stitch, so I am going to try that. If it looks bad, I'll pay someone to do it again. I like putting the quilt together but not quilting or binding. I'm not an all around quilter yet.
