First I die I bought was a hex die, to make a double bed size grandmother's garden quilt. What a God send! I was in love! I bought others as they went on sale. After several years, and many dies, i can tell you the ones I use the most are the 2.5" squares (qty 9 on the die), and the double 5" square die. They help keep my scraps organized and make beautiful scrap quilts. My next choices are BOB's or "blocks on boards". Over the years you will collect and use many, but you have plenty of time to think about it. Enjoy your new toy.....Jane
