Liquid lame can be found in most fabric stores, but usually not in that many colors. But normally I see about 3-4 at the Yardage Town closest to my house. I made veils out of them sometimes, they flow really nicely.
If you're making a circle skirt, you probably don't need 1 1/2 circle, you can just cut 2 half circles, that will be full, and because it's not see through you don't need more.
And because it is cut on the hem, I agree with letting it hang for a couple of weeks at least. Don't touch it, or play with with before you hem because it will fraye like crazy.
