Harry Potter Day costumes (gasp)

I've got two new projects! I'm sewing two pleated skirts, one for Harry Potter Day, the other possibly for the Harvest Fest at our church the night before. Work on my GoF cloak will resume soon, and i plan to sew one skirt (a charcoal with subtle burgundy stripes that are perfect) to wear with the cloak (to the premiere of GoF as well) and the other is a turquoise and orange polyester plaid that i'm considering wearing to the Harvest Fest clad as Kitty from That '70's Show. Pics will hopefully be forthcoming.
