My favorite ruler is a Creative Grids 2.5" x 6.5" ruler. It gets used as much as any other ruler I have. I had been looking for one to purchase for a backup, mine was misplaced for 6 months. We went to quilt show the end of August and a vendor had them for $7, I bought two (so now I have a backup for my backup), I have paid $8.95 - $9.95 for one. Almost everyone in my guild has purchased this ruler after borrowing mine to use, it is that useful.
