I've only made one so far. I starched the flannel heavily and cut 6 inch squares. I did sew the X and did not use batting. My seam allowances were 1/2 inch. I back-sewed a few stitches at each "intersection" when I was sewing the rows of blocks together and I sewed around the perimeter of the finished quilt twice. It came out nicely, but next time I think I would consider a larger seam allowance. Good luck with yours--they're fun to make!
