Tammie Bowser...Yes this is the lady from Simply Quilts many years ago! She sells a grid on a mat where you can draw your own lines on any stabilizer, or you can buy the "Quilt Fuse" pre-drawn squares on the fusible in either 1.5" or 2" squares. Occasionally you'll even see 1" squares, but I'd hate to try to make that one lay flat. BTY, I found a nice lady from ebay who also sells on her own website, some of the fusible grid cheaply:
