I never knew your could draw a quilt on Excel but I have a very old version 2003 of Office. Do you have any quilt magazines to see how published authors deal with writing instructions? I make most of my quilt on my own so there is different ways I go about creating the blocks for a quilt. You might even want to invest in Electric Quilt program. Many quilter here are still using version 5 which can be very reasonable in price. Good luck.
