When you’re the weird kid and nothing in financial reach suits you, you learn to sew pretty early.  Martin and Christina made so many costumes long before cosplay was even a word.  For approx 7 years Christina was a costumer for other productions as part of her income.  When she sewed through her finger during a production of The Boyfriend, she decided that sewing for herself and working along side Martin to sew outfits for acting gigs, was more to her liking.
There is no more sewing for other people and the focus is on creating characters and outfits that bring them forward in building and performing.
