If you look at your local Quilt Shop in the quilting section, you will probably find quilter's pins. I perfer the ones with the flat flower heads over the round ball heads. They don't make a bump when you pin 2 pieces of fabric together. The flat pins were also recommended for a Stack & Whack class I took. You need the flat ones so that when you do your cutting with the ruler, the ruler lays flat over them. Someone also posted here that they now make round head glow in the dark pins. Nifty!
