I've been doing the Stack and Whack quilt and for the most part, my pieces go together pretty well, but I have had some issues with wavy pieces (which will not be part of the quilt, good thing I had extra fabric!).
Anyway, should I use sizing spray before I cut the triangles? Any advice appreciated! (Sorry, still very much a newbie, been at this for about 3+ weeks now) And now, I'm about to work on the solid triangles now, to join with what I've already made.
