Have you seen the new trick, or maybe old, (new to me) where you face the binding with muslin. The muslin is about 1" wide and the real binding is 1 1/2" wide, if you're using the folded binding that is 2 1/2"wide. The muslin is on the inside and never seen. You seam it together, fold as usual and stitch it on. Saw this in mag or online, can't remember which. Next time I'm short on binding I'm going to try it.
