This is a part of a challenge quilt I'm working on in a contest being run by my guild. I'll go into great detail about all the rules and show the finished piece when it's done, but for now, I need advice. One of the rules is that you use wood, plastic, or metal on your piece. I've got a bunch of wonderful color-coordinated buttons in all the colors that are on this quilt (it's a mini). Should I put those buttons ON the patches where the X's intersect? Or should I put them on the white sashings where they intersect (and thus cover up some un-matched seams)? My original intent was to put them on the sashing - sort of like cornerstones - and then I wouldn't have to worry about those seams.
