Oh, lady! That looks absolutely planned!
I know how you feel about using "not my usual choice" of stuff. From an early age, my mother shared the reality of her growing up years through the depression and WWII ... long before someone called it "recycling" ... I could see the common sense of it, and it KILLS me to think of all the stuff the thrift stores throw away because they can't sell it ... or the jeans have too many holes, but I can still get pieces out of it ...
I think your quilt looks just wonderful! And, you just keep busting those scraps! LOL
