On my next quilt I'm going to try cutting all my pieces just a little bigger and squaring as I go. These last 2 quilts (my first 2 still working on the second) have been very difficult because when I am done making my blocks they vary in size between 12 and 12 1/4 inches. So I lose a lot of points and overall I'm probably the only one that notices them but I do notice. Would love to make a block that didn't have to be trimmed, it would also make the sashing and corner squares and borders etc. go a lot smoother.
