That is one gorgeous quilt. Wow. So much work and it's beautifully done. I could look at it a long time. Borders on big quilts can be so tedious. You could simplify and just do two--and make them a bit wider so they are manageable. I can't wait to see it done.
I just read the 9 patch blocks are 1.5"?? Wowzers--just amazing.
