I stumbled upon the lovely work of Marie Bushbaum on Behance the other night. She is an extremely talented pattern designer. But what I love most about her work is her presentation — she includes tons of illustrations showing how the patterns would be applied to actual products. See the rest of her portfolio here, and take a look at her blog, another new find for me.
