Both of those are beautiful but not what I'm looking for. I suppose the best I can describe the way the blocks are is somewhat like the jigsaw pattern that the shapes intertwine. The tessalating patterns seem to be the closest.
I'd love to post a picture but the description of how to do that is beyond my comprehension. Why can't we simply copy/paste?
As to the thing of it being 6 blades--each FINISHES at 2 1/2" so would be cut at 3" and there is a triangle shape background. If that helps anyone. I'll continue to look with the tessalating suggestions. Seeing some really pretty quilts doing this!
