Born and raised in the American Deep South, Misty's career in elder care took a sharp left turn when she was swept away to the land of Robin Hood by her very own Merry Man. She's a coffee-swilling master of stitch-witchery with a magical touch in the kitchen and a neverending stream of Disney gag reels playing in her head. A certified nursing assistant by trade and a toy aficionado by choice, some intense parenting ensured she was well versed in gardening, carpentry and electrical engineering by the time she entered grade school. Her culinary artistry, tool-wielding wizardry, and skill with needle and thread were honed over nearly four decades in the kitchens, workrooms, and outdoor spaces of family, friends, and clients. Voracious reading took care of the rest.
