So, I made the skirt - I'm very pleased with it. Considering that it was a rush job and I've never actually sewn any clothing before, I think I did a good job. I used these instructions to make my skirt:
They were very well-written, and the measurements were perfect. The radius calculator doesn't work, though, so you'll have to figure that out yourself. Also, for the part where you are using string to draw your circles, after you draw the circle that equals B+C, you should cut the string to the measurement of B, *not* C. I think that's a typo. At any rate, the lady gets two thumbs up from me. For anyone interested, she also includes instructions on how to make a handkerchief hem skirt.
Here is a picture of my skirt:
I made it out of silver tissue lame, which was a colossal pain in the a** to work with. It's pretty, but it kept snagging on my needle, and it "sheds". I will not be using that again. I will use the remnants to make detachable circles to line the inside of the sleeves on my jacket (see pic below).
Here is a picture of me at the performance tonight:
You can see what a big difference that silver underskirt makes. The effect was lovely, especially when the whole ensemble was paired with a black lace beaded cover up that I just bought from an Indian gentleman at a fair. Sorry the picture is so dark. We were outside at dusk.
I will definitely make more of these skirts, now that I see how simple it is. No way am I going to continue to pay $35 and up for these babies!
