I always end the year with a lot of random bits and partially used balls of fingering-weight yarn.  Magic Ball Cowl is the perfect project for using a bunch of these bits and pieces.  This simple, textured cowl features panels of stockinette, a 12 stitch reversible cable, and linen stitch.  The result is a subtle pattern of vertical textured stripes combined with the horizontal stripes which are a result of the color changes within the magic ball.
Normally, I would agree that there are no knots in knitting. However, the magic knot is an excellent way to turn lots of tiny balls of yarn into a larger ball.  A magic ball will provide you with lots of surprising color changes throughout the project.  I was inspired by Katie of Inside Number 23, who did an excellent blog post about making a magic ball.  Here are some links to magic knot tutorials:

Of course, if you prefer a monochromatic look, Magic Ball Cowl would work well in a solid or tonal yarn too.
