I've always had a bit of a fascination with masks and costumes. I think everyone does, in a way. I think it's because people are so used to putting themselves and others in boxes, thinking they must behave this way or that, staying one way, or being one way, without making drastic or dramatic changes - but when in a costume or in mask, a person can choose to be or behave however they want. Hiding some aspect of the usual personality somehow gives us freedom or license to change. Give someone a mask and they show sides of themselves that they might be too afraid to show when their face is exposed... 'give a man a mask, and he will tell you the truth.'
Or maybe halloween candy has conditioned us into loving running around in a costume. Oh, glorious instant gratification of delicious sweets.
Heh, but speaking seriously, my fascination with masks and what people hide behind them has led me to create masks and accessories that don't just hide truths behind them. They each, in their own way, say a little something, be it about me or about the wearer; Each mask tells its own truth.
