I first learned of Scribble Knitting in the August 2012 issue of Knit'n Style magazine.
There is an article by Lorna Miser, describing some different techniques of Scribble Knitting, along with a pattern for a cowl.
The basic idea is that you use two vastly different weights and textures of yarn; work so many rows in one yarn, then a row or two of the different yarn to create the 'scribbles'.
The second, contrasting yarn must be carried up the side when not in use, and on some rows, it is necessary to slide the fabric back to the opposite side of the needles so that the correct yarn can be picked up and knit with. Because of this, circular or DPNs are used in Scribble Knitting.
I had to try this out for myself of course. At the yarn store, I chose my first yarn: Crystal Palace Merino. I asked the shop girls for advice on my second yarn. It was suggested that I use a ribbon yarn. However, as they did not have any ribbon yarn, and I don't care much for it to begin with, I decided to go with some luscious Malabrigo Worsted. Also, I don't like to follow the rules, and wasn't looking to make anything too outrageous. I wanted something I would actually wear in public. And again, not liking rules that much, I did my project a little differently than any of the methods described in the magazine.
Once home, I started on my project, and knew I had made the right choice in yarn. I love my wrap/extra large scarf. Although it is very light and airy, it is pretty warm. It is perfect! I can't wait to play around with some other types of yarn and see what else I can come up with! Here is a picture of my project, and the pattern is available for purchase in my Craftsy store.
