well, I've watched the video on youtube and found it so easy. One block with 3 fabrics, the same block reversing the colours, and hst's on the ends of each row. I want the ruler she used in the video, it would save lining up the edge of the fabric for every cut. Anyone know what it's called and where to find it?

2 1/2" shape cut ruler. I want one too. Im not sure where you buy them at.
