I'm a scrappy quilter and got started with 6 1/2" charms on eBay. I guess I must have been lucky because I made 9 quilts (double and queen sized) and every one came out right on the money. Am now branching out (after I finish binding my current scrappy which is a generous queen) and ready to start a OBW. I really don't care for cutting but sure like everything else about making a quilt!
