That's about it AnngelAnne, your UNfinished block will, or should measure 10 1/2". This is YOUR block, whatever block is chosen, hopefully it will be a learning experience for all. If there's a block that you think might be difficult, just holler, there's always help. There are no 'quilt police' lurking..lol If ever there's a block you don't want to tackle, skip that month and rejoin later. Hope that helps.
