Ah, here's the one. I knew I had it somewhere....planned to use it for the bear paw that my son is anxiously awaiting. Now you can make your own and see for yourself if they're helpful. I've used these for a sample block and I was very happy with it. My only problem was that the pattern I used for the triangles was small and not that straight when I cut my squares, which made them look off even though they were on point.
Hope this helps. Happy sewing!
