I forgot to give credit to Margit Lohrer at Morehouse Farm. The idea is in her beautiful book Merino Knits. I hope I didn't infringe on her copyright!!!! She seems generous with her patterns. GULP.
I do recommend her book highly, their yarm is awesome, and her customer service is what I look for in a supplier. I have made several things from her book with fabulous results, and I love her approach to knitting.
