No, not leftovers from dinner, leftovers from quilting. I recently finished two quilts that used tons of scrappy half square triangles (I can't show you those two projects just yet). I always make some extra hst's to account for little mistakes and to give me some different choices to try out. With my leftovers I was able to make two little quilts.
I arranged the hst's in a sort of random way until I was pleased with the color distribution. The hst's are 1 inch finished, borders are two inches wide. The finished quilts measure 9 inches square and will make a cute display on a little table, maybe with a tin candle holder in the center.
So save those hst's and make a "leftover" quilt.
