I think I missed something, but not sure. The Pebble Filling Stitch is worked starting 8 threads above, and 12 threads to the left, of the top corner Diamond Eye. As I stitched the stated 6 stitches beyond the right corner Diamond Eye, I am wondering why the North and South spaces are 6 threads beyond the Diamond Eyes and the East and West spaces are 10 threads. Just wondering. Thanks.
