It is a beautiful runner. I haven't read this entire thread, but offer the following hoping not to be redundant: Please attempt to draw it on a piece of graph paper. If you look closely, it is a 6x6 patch - 2" grid for a 12" block. You can see enough of the pattern to draw it and then erase the appropriate lines. -- I am sure you can do it.
Let us know. Good luck. Suz
