Well you're pretty far along for most of my tips, lol. And I've already posted most of my tips; I think the best one is to sash each block instead of using long sashing strips. I can help you choose the right fabric, but you're past that. If you have questions I'm happy to help, but I'm not sure what other tips you're looking for?
Regarding scalloped binding. My tips for that are 1) don't make your scallops too deep. I actually think my scallops could and should have been a little shallower. 2) Cut the binding on the bias, obviously.
3) When you're attaching the binding to the quilt, don't pull the binding. 4) The binding will curve easily around the outer part of the scallop, but when you get to the inner V, it helps if you pull it kind of straight. Clear as mud? And of course, do
not cut the scallops until *after* the quilt is quilted.
