If you would like to make XX and/or OO without paper piecing, try this link Canoe Ridge Creations.
While following a lead from another blog I found this tutorial. So much easier than the paper piecing. Wouldn't you know I finished the blocks yesterday. Today I'm rearranging, and tomorrow I hope to start sewing the blocks together. That's my kind of timing finding an easier way when I done doing it the harder way. Oh well. Hope this find helps you out.
