As you can see, my block is not perfectly square. It tends to bow a little at the middle row. I do not trim it because this is caused by the fabric stretching. When I sew the block into the quilt, I just keep the edges of the two pieces I am sewing even with each other and stitch a quarter inch seam. Once the quilt is completely finished and washed, it all looks fine. I use unwashed fabric when I am quilting so the fabric shrinkage outweighs any wonkiness in the blocks themselves and the washing helps bring the fabric back into shape.
