Cathy Costa is the owner of BP yarns, a virtual yarn shop for Plymouth yarns. BP is an abbreviated version taken from her other shop on Etsy called Babbidge Patch, a place where you can buy some really adorable knit hats and scarves.
Cathy lives in Falmouth, Maine and has been selling her yarns on Etsy since 2008.
I love the bright and cheeful colors and textures of her yarns, especially the novelty ones with the slubs, lumps and bumps. Be sure to check these out.
