Snail's tail
I would like to make a 12 1/2 inch snail tail block, First step, make a 4 patch square, using 4 squares measuring 2 5/8 inches. Why would I need the extra 1/8 inch? I know why I need to cut my squares to make triangles bigger but why the squares? Does not say to square up 4 patch, or at any other step. It does say use 1/4 inch seam. The sample I made looks strange LOL. My main concern is I do not have a ruler with a good 1/8 mark on it. That may be why my sample blocks looks strange.
