The best thing about costuming: There are so many costumes to build. Costuming is such a flexible hobby. When funds are tight, I can find something to build. When I can get extravagant, I can find something to build.
The worst thing about costuming: It is addictive. Every costume I build, every movie I see, every book I read, every dream I remember leads me to another dream project. Another costume on my to do list.
