This pattern emerged after looking for ways to use up small scraps of yarn. The hoarder in me could not throw away those lengths of yarn after sewing up, particularly if it was yarn that had been hand-painted or perhaps was quite expensive. There are quite a few attractive scarves that use similar techniques; I would not claim to be the originator of this idea. However, what I wanted was a knitting stitch which allowed splashes of different colours from the odds of yarn to get mixed in with each other and yet also provide a reversible knitted surface. With this in mind, I began to experiment with slip stitches and eventually came up with this simple pattern
