Momo is a fantastic knitter with a droolworthy project page on Ravelry. She tackles difficult colorwork projects quickly with ease, has great color sense and almost always uses fabulous hand-dyed yarn. I was beyond thrilled to see how she creatively translated the charts from Elektrocute into a full pullover!
In addition to expanding the charts to fit the length of the sweater, Momo made the background a gradient progression of grays which I think would look great in the cowl too! According to her project page notes, the pullover is top-down, uses the contiguous sleeve method and the zipper facing is steeked.
If you love a colorwork chart but don't like the item it's intended for, why not modify? A cowl chart can be turned into a full sweater, a mitten motif can become the motif of a circular yoke cardigan, or a full sweater chart can be scaled down to a hat if you are dipping your toes into stranded knitting and want to test out a smaller project first. Knitting is full of limitless possibilities if you are open to making modifications and coming up with creative solutions to get the projects you want. Go forth and modify!
