Loy Shawl is a great way to use up left over yarn. I enjoy knitting socks and scarves and often find that I have various left over yarn. Often, they are in similar color ways. Loy is a shawl that allows you to use up all of those leftover pieces.
If desired one color may be used as a base or both could change depending on what you have available. The shawl may be knit in any weight of yarn and you can add repeats or remove repeats as desired.
