Have you tried the cutting geese method where you place the small squares in the corner of each side of the rectangle? That is the best way for me to make a flying goose. There are a couple more different methods besides Eleanor Burns ruler method that you might find more desirable. Go to YouTube and type in Flying Geese methods and watch some Tube on it. I bet you will find something better and your ruler won't be an issue. As for the invisigrip. I bought a lot of it and put it on all of my rulers. Yes, it's not real sticky like I wanted it to be. In fact, at first it seemed slick. Now, it works better after I've used my rulers more. The sand paper worked better but I didn't like the look of it and how I couldn't see through it. Now I lean on my rulers and put my hand on my ruler and the table both at the same time and put my rotary cutter next to my ruler, not pushing against my ruler at all. It works well that way. Hope this helps.
