I loved the gray maxi skirt I made (here) that I decided to make a black one too! I know the picture isn't the best quality, but it looks great. I adjusted my measurements and this one fits me much better. I bought the black knit fabric at Hancock Fabric for $10 (2 yards at $5/yard), and the 2 inch wide elastic was about $2, plus tax my total was only $13! Not bad for a nice black skirt. The original tutorial came from Sew Much Ado, which is a great sewing blog you should check out if you haven't yet!
