Peckish, correct me if I'm wrong, but the blocks are made with a diagonal cut once, not an "X", or were you speaking of something else? I made the blocks the size the pattern called for and I used a fabric already prepped for the posy and had cut off my borders before matching pattern and I only got 40 blocks. Luckily, I have more fabric. With the size called for by the pattern I will need about a 15 inch square for the set in triangles and I'm thinking I will need about 30 more blocks. I am going to try to incorporate the borders(already cut) into the pattern also.
