If I was an applique person this would be THE tool for me. BUT since I am not an applique person I shall let another get my set of rulers. On the other hand that idea about a carpenters chalk line is a great idea! I shall have to see what the price of the silly things are empty at Home Depot or Lowe's and how much the iron off chalk is. I don't need the other stuff that is offered with the purchase at her site. Thanks for the link...
