When working in the end pieces, and or if you have a few extra pieces that you want in the borders, you just need to cut the boarder strip on the 60 degree, a bit of math will be included in figuring out how big your strips are to match. that is for the ones that have the whole piece into the boarder, the other edges, the pointy ones, it is best to use the other end of the super 60 if you have it and measure what size strip you need and then cut the triangles from that. I will have pictures tomorrow. or you can line your ruler up along the pointy ones and cut them off.
