I am in no way affiliated with the company that makes this ruler. I just ordered it Sunday from Amazon using my points and it only cost me $2.70. It seems to be a very well made ruler and I can't wait to make a large log cabin quilt. I have made 3 or 4 of them without this ruler and had trouble with my blocks always coming out the same size. This should solve the problem. Anyone have this ruler? Does it do what they say it will?. Thanks.
