I did it!!!
I stuck to my original goal of designing a fun doily that used only the techniques that can be done with one shuttle and a ball thread. No fancy 2 shuttle work! There is some celtic style overlapping, but that is really not hard.
I've prepared a 4 page pattern with a file size of 2.2MB in pdf format. It contains written instructions in English, and several partial diagrams. I'm offering the pdf pattern for sale in my etsy shop.
The doily looks nice in white, but there is also a lot of possibility for color play!
