A friend of mine sent me a Rosie the Riveter bandana, but it was a tad too small for me to wear that day (in support). However, I decided to make my own, but with a twist. I took out my Van Gough Tardis fabric and made myself a 24 x 24 inch bandana with narrow hems.
If you've never done a narrow hem before, this website gives you some good techniques for achieving a nice narrow hem: http://foursquarewalls.blogspot.com/2014/05/narrow-hem-three-ways.html
After putting up my hair in pin curls & messy bun, I tied the bandana around my head.
This is the first time I did my hair in the fashion. I followed a YouTube Tutorial on it, which worked out well for me. I plan on probably doing this again.
And I think I'll be making more Geek-related hair bandanas for myself in the near future. It's a nice way to show off a bit of geek, and use some fabric that I wouldn't otherwise use.
