I love making these makeup/cosmetic bags. I've probably made close to a dozen by now. They take me about a half hour after I'm done cutting (2 each of outer fabric, lining, two kinds of interfacing, so it's like 8 pieces).
It's such a versatile pattern and can have so many different looks and uses. Use a fabric with sewing supplies on it and it's a craft pouch. Use flowers and it's girly. Use fabric depicting the New York subway system, and it's got some cool.
