Then if you are going to quilt instead of tie, then that is great. That is the best thing about crazy quilts...they are so individual and personalized in the way they are made. I'm sure that your idea of quilting instead of tieing yours will work out great and there is just no right or wrong as long as it works. I really do think that your layout, pattern and colors are so pretty together. I can hardly wait to see it done. I have made several scrap quilts that are strips layed on muslin the same way of making a crazy quilt, but without all of the fancy stitching either and I do a free motion stiple on those. They are a bit heavier, but they still quilt up great, so you shouldn't have a problem with your crazy quilt for sure. Just have fun with that beautiful quilt.
