I got all my strips cut and then I fussy cut my panel. I thought I was doing such a good job making short work of it...but when I laid my fussy cut 8 1/2 in squares on my cutting mat...oh noooooo...they weren't square. :(
So I guess its finally time to buy an 8 1/2 in square ruler. I have looked at a couple and think I am going with the Omnigrid Omnigrip ruler.
