Looking for a certain sock kit/pattern that someone here showed off a while ago.

I can't remember how long ago, but someone posted these beautiful socks they made from a kit. They had some complex lace/cabling, beads in the cuff, and the most notable thing was a multicolored stripe down the side that was supposed to resemble stained glass. It was designed based on a book that I also don't remember the name of.

The OP linked to a different website that sold the kits (but they were out at the time). Searching google and r/knitting didn't turn up anything, possibly since I don't remember enough key words about it to properly refine my search =/
