Color Loops are a way to knit with stranded yarn vertically. In this book, I describe how I got the idea to use Color Loops to knit with color and texture. In the How-To section, there are instructions on how to set up the Color Loops and I knit a swatch sock tutorial that combines four of the basic designs. This is followed by 23 designs using Color Loops on socks. The best thing about Color Loops is that it is surprisingly easy! Other positive benefits of Color Loops include how the knitting remains stretchy, has no heavy or extra thick yarn floats, and has an attractive back side, too. Each design has a swatch sock photographed on a foot model, and another photo where the knitting is shown wrong side out. Many of the designs do not require any chart to follow, but if it helps to visually represent the design, there are charts to show the pattern. There are other vertically stranded knitting techniques out there, some of them with a long history, but this new technique gives a solution to the challenge of juggling different colors of yarn, and without the problem of having to weave in lots of yarns ends at the end of your project! This new way of knitting with color and texture is perfect for knitters of all experience levels. Although it can’t replace the ways we already knit in traditional methods, there are lots of possibilities to explore with the new world of Color Loops!
