I acquired about 30 of these 12-inch blocks, they are all hand pieced, and consequently, not completely consistent in size and/or shape. Some of the inconsistency will 'quilt out' and be fine, but in cleaning/pressing them, I realized some are off in size by as much as 1/2 to 1/4 inch. I need advice on how to ustilize all the blocks in a single quilt and get them to 'fit'. Should I border each one and then trim to a consistent size? What other advice can you offer so I can use them all?
