This pattern is from a book called "Yarnplay" by Lisa Shobhana Mason. As far as I know, this pattern is not on the internet.
I have already done the following inst. (Bind off 6 sts at beg of next 2 rows.) AND the beginning of the ones I quoted earlier (Bind off 6 sts at beg of next row). Now I have 52 sts left on my needles.
