Every year I make a new sweater skirt.
Start off with an old sweater. The bigger the sweater, the easier it will be to work with (I like to use mens sweaters). Stripes are also a nice way to kind of cheat, they provide you with a nice guideline.
Turn the sweater skirt inside out, fold the top over a half-inch to an inch, and use a seam ripper to make two little holes in the front area of the skirt. This is going to be where your drawstring will be.
I used a piece of the sweater for my drawstring, but you can use ribbon, elastic, or anything that will tie and hold throughout the day. Carefully take your drawstring and stick each end through the newly made holes.
Sweater skirts are so easy to make. I love them with long-sleeved tees, tights, and a little hat… soooo fall.
