Years ago when Thimbleberries was all the rage, fabrics, patterns, clubs, etc., I bought a Creative Grids ruler that has the 7/8" marks. Lynette Jensen, Thimbleberries creator, used 7/8" in all her patterns. Well, Thimbleberries is no longer popular and I still have that ruler. It is in the tote with all the "specialty" rulers I just had to have! I also have yards and yards of Thimbleberries fabric in my stash. I loved it at the time.
