I have the half square triangle set 1 1/2 inch to 6 1/2 inch, and the flying geese set- up to 4 by 8. I used the 4 x8 today, and i also need to make 6 x12, but didn't have a bloc loc that big. It was a real pain to get accurate flying geese, compared to using their rulers. They are great. I also have the strip ruler, but don't use it very much.
