[QUOTE=dlbuthfisher;7883078]I'm starting my. Iargest project yet, I'm self taught and need help calculating fabric yardage. I'm going to make a Nordic star quilt (full/double), with sashing, so I will need 15 - 12" blocks. I've found the block pattern here, scroll down for the large star:

Welcome to the forum! I looked at your link, did you notice she states the block is 13" unfinished? This would make a 12 ½ " finished block, which is fine as long as you aren't planning on combining it with 12" finished blocks.
