I love my electric go big......and every time the dies go on sale, I buy 2 or 3 or $100 worth to get free shipping. Over the years I have accumulated a lot of dies. I use the BOB boards and the swap boards are the ones I use most. Swap boards are the one's I "swap" with other quilters.....2 1/2" (qty 9 squares on the board or 56 cut squares in one pass when using 6 layers). I also "swap" 5" squares for I spy's...2 sqs per board or 12 squares per pass. I also swap postage stamps (1 1/2" squares). everybody uses different boards, and I didn't buy them all at once. But I do love them. Oh, Oh, I use by 2 1/2 inch strip cutter alot because I store many scraps as 2 1/2 inch strips.
