Okay heres the scoop. My mother is doing an ohio star. She was working on it and for what ever reason put it away and now has decided to work on it again. She has a block that is made up of 4 triangles. Not all triangles are cut from the same block. Shes forgotten what size she has to cut her original block so that when she puts the new block together it finishes to a 6 inch block seams and all. Can any one help ? I know she would really appreciate it. Thanks.
