I decided not to go.
So, now that I will have more time...
I am a bit scared that I am actually contemplating a
quilting fabric of black with orange flames, for a costume lining.
If I win the fabric, it should make the interior a bit interesting. The outside is mostly deep blue background, with lots going on in appliques in reds, orange, browns, and some silver, and even some sparly bead trims and sequins. More art-to-wear than costume, but it started as a costume idea for a larp character.
If I don't win it, I may go with a basic orange interior, try to find another flame fabric, or opt for a simple cool blue. Not sure which yet.
