The question of sizes comes up often. You can make it whatever size you want. Google sizes and that is a starting point. But, depending on the finished size of your blocks, sashing or none, what size borders and how many, and (I think most important) the design layout of the blocks will determine how big your finished quilt should be. We all promise that there aren't any quilt police going to come to your home and measure your quilt - have fun and just be creative!
