I ended up using black cornerstones to make sure the alignment went well. Decided to let the pro quilt this one. I REALLY wanted Charisma to quilt this! We discussed and agreed on pattern sort of informally..... then I chickened out of mailing it cross country. (this is the first time I've kept a quilt and really don't want to trust it "en route") Sure hope the locals are 1/2 as good as Charisma..... I LOVE her work
