Thanks, Brink and Margo - Everybody actually!
So here it is again: I get to make all the choices and decide how how I want my quilt to look, but I also get to do a little work first. Like the shrink test Margo described.
Maybe I'll do the work when it really matters. Maybe I won't when it doesn't matter. And then I'll just enjoy the ride and all the surprises that come with it!
Prewashing is probably safer, especially if you also test for color transfer, but that's not my style...
I'm layering a pineapple right now with Moda mottled black flannel. I'm going to leave it unwashed, but I'm going to starch it to within an inch of its life. I'll let you know how it turns out.
