Thanks for the nice compliments. No I did not sew the x in the center of each block. I started out with a 7 inch block of cotton, flannel and cotton. All cut 7 inch square. I used a 1/2 in seam. So ended up with 6 inch block. So far I have made 4 of these. Most of them I made 9 sq wide by 13 sq long. On the ones that I only used two colors on I bought 4 yards of each color and 4 yds of flannel. Hope this helps. If I can be of anymore help to you just ask. They are really easy to make.
