So. This took FOREVER, but it's SO worth it. I finally made my 25 yard skirt. It was based on this tutorial. http://www.craftster.org/forum/index.php?topic=404957.0
I decided to to a drawstring waist with some bias trim from a child's skirt that was falling apart rather than using any elastic in the waist. Also, I added some trim to the top panel, as somehow during this process I managed to get a big tear horizontally along the belly. I wore this to my class yesterday, and the gals loved it! I hope you will, too.
