The light sage blue-green one was designed as part of a set of thread pendant cords published in the book, Jewelry With a Hook. They were all made in size #20 crochet thread. Due to a mix up, it was not included in the book, nor was I paid for it. I think it’s pictured or mentioned in the first edition though. So I retain the rights to it and over the years have tried variations of it.
The pink one is size #10 thread. The gold beaded one is size #5 (fingering wt) hemp yarn.
