I made a skirt to wear with my Halloween costume. I just grabbed whatever fabric seemed like it would work for the costume and used this skirt tutorial to make a gathered skirt with a waistband. It was simple, and pretty quick, considering my machine is in the shop and I was using someone else's. I've done enough gathering and blind hemming that I was able to mostly whip it out.
And, my kids are cute. I think I only made one of them cry while getting ready for church!
