It didn't take as long as I thought it would to sort out the mixed up blocks in the starburst quilt. And once that was done, the quadrants went together like nobody's business!
Now that centre is perfect, and all this top needs is some borders. Then it's up to Mom's for quilting. The long arm machine arrived last week and she's been practicing since then. I think she's been looking forward to having a real project to quilt!
