I made this skirt out of leftover black and purple knit I had. I'm sorry I don't have instructions, but it was super simple.
All I did was cut long, rectangular strips out of the knit, about 4x24. Then I sewed the strips onto a piece of cotton. and sewed the cotton to a piece of knit for the back of the skirt. Then I put an elastic band/belt over the top. the end.
