I’m an animal-loving, language-learning, picture-taking, mineral-collecting, videogame-playing, modern rock-listening, celery-hating, acrylic-painting kind of gal. I love contemporary fantasy books and am a sucker for powerful women with magical abilities. When I’m not hunched over my computer writing (while my cockatoo sits on my shoulder begging for head scratches), you can find me hiking, playing DnD on the thrilling new podcast, Of Dice and Friends, or hanging out at Indie Fantasy Addicts, the greatest group on the internet, where I chill with readers and generally stir up trouble.

Sarah learned to crochet in 2015, and in 2017 she decided to meld the two passions together. Since then, crochet cosplay has become their signature, and every cosplay has at least one crocheted piece incorporated within it. They are now a Masters-level cosplayer and compete with yarn as a primary medium. Sarah is a plus-size, neurodivergent, queer cosplayer who advocates strongly for cosplay as a form of self-expression. Cynthia is the backbone of Stitched in Starlight Cosplay, acting as Sarah’s full-time convention helper and a (willing) participant in Sarah’s duo cosplay ideas. Cynthia is known for being the Con Mom™ who cares for anybody and everybody, and her sense of humor never goes unnoticed. Sarah and Cynthia love bringing character duos to life and showcasing their love and friendship for one another through those iconic relationships.
