Thank you for your compliments I didn't follow a pattern but I did get the design idea from a Japanese jewelry-making website. However, if you visit Beadwork.About.com, they will also have tutorials on right-angle weave (or RAW) that include this design idea. I'm searching for a direct link for you and I will post it to your page as soon as I find it.
This is SO BEAUTIFUL. A work of art.. how clever. I have tried and tried to do a cross like this but so far I have been unsuccessful. Is this your own design or did you follow a pattern?
