Thanks for sharing this information. I will be checking out this ruler as I need all the help I can get. LOL

These rulers have intrigued me for a while - did not like the fact that a different size was needed for each trim. However when visiting a local quilt shop she demonstrated that if you purchase the 6 inch half square triangle ruler it is possible to trim all sizes simply by aligning the ruler - trim 2 of the sides then slide the ruler to trim the other 2 sizes. This is now my favorite ruler and the half square units come out perfectly.

I use the 6 inch one for all my hst. I rarely make any over 4 1/2 inches. I don't see the reason to have one for every size. I have the strip set one too. I will get the flying geese one when and if I ever sew any. Usually I make hsts for my flying geese.
