I love this board, everyone is being so helpful, thank you so much!! I'm going to grab a 12.5 x 12.5 ruler if I can get to my LQS today, try some of these methods with scraps before I start with my nice fabric. Everyone is so nice, I mentioned my plans to someone local and they started to tell me that it wasn't possible and to make another pattern. Don't see why you couldn't make large HSTs
