Jelly roll skirt - take 1

As I watch reruns of project runway, I am deciding to try and go with this.  So, I just finished a jelly roll skirt with Ticklish by Me and my Sister for Moda.  I used a website called www.chicaandjo.com.
This website has a link to determine the amounts of fabric that need to be cut for any size tiered skirt.  You put in the waist size, length, number of tiers, and voila (sp?), directions on how much to cut for your skirt.  My skirt for the oldest, came out cute, but not as "twirly" as she likes.  This was my first attempt, and I am notorious for messing up the first draft.  I intend on doing the again, with a few modifications.  (My gathering was uneven)
All in all, it was a cute skirt (even with all of my mistakes!)
