Thanks to everyone for the compliments. They are not too hard to make, just takes some concentration, and having 2 people to help cut is a +. I wish that I had done one of these before I tackled my bargello, because it is a smaller version, and an easy way to start. They measure about 20x40. I have just ran across another runner, that uses this same ruler, so am going to cut it out and will post it when I get it done.
