A friend of mine loaned me a book (Quick Watercolor Quilt's by Dina Pappas) for the section on piecing with interfacing. Where you lay out all your fabric square adhere them to gridded interfacing and then sewing it all together. First does it really work like they say? And second, it seems a little like "cheating", of course it's not because there's no right way to quilt, still I just don't know about this techinque, any opinions?
