So, I don't mass up any more fabric---- I need help figuring out something for a block size. I need a 12 1/2 inch (12 finished) block. It has two 6 1/2 blocks (one each of two colors). The other two blocks are half square triangles. How do I figure out what to cut those for? I am sure this is pretty easy, but I am getting frustrated. Thanks so much for the help!! :oops:
