I made a ribbon bow-tie a few months ago, but I never did anything with it. I simply used a two inch wide wire lined ribbon, about four inches in length. Sewed the ends together, then did the same with a quarter inch silk ribbon, about an inch in length. I slipped the smaller ribbon over the larger ribbon, and wah-lah, a bow-tie!
When I got home from work today I decided to stick a hair clip through the back, and make it a hair bow-tie.
It's a great size for my head, and considering how easy this was I could make a bow to match every outfit!
Happy DIYing, chris!
