I also cut out two big rectangles the length I wanted my skirt to be and the width of my waist so each was big enough to go around me by themselves. I wanted a full skirt so I sewed these together on both sides making a large tube. I gathered up the top and sewed it to the waist band, leaving the ends of the waist band loose so that I could tie them. I had to stretch the waist band as I sewed it. The finished skirt took less than 30 minutes to make (although I still haven't hemmed the bottom).
I like it best as a high-waisted skirt tied on the side. (For me, my natural waist counts as high-waisted since I usually wear everything on my hips!) I realized later that the skirt is quite versatile.
It works as a comfy summery top if you put the ties in the center above your bust and tie it behind your neck. I was surprised at how much I liked it that way since I never intended this to be a top. I also like it lower on my hips although it isn't as flattering!
