Since I do not know what a "setting fabric" is I am no help there but I wonder if you could use what you made for a nice long body pillow that is cozy to rest against for your own use or a table topper -- or use the squares you made on point and build out with other fabric into a upper and lower rectangle attached or 4 large square that could be 2 upper 2 lower corners. Wish you the best of luck.Zoey
