Two college friends, Gwen Weinberg and Anita Nadelson, started Seattle's Three by Three over 10 years ago. Their product line has been evolving ever since, and it's been written up everywhere from Real Simple to Domino to Living Etc.
Three by Three's products includes home, office, and school products. They're practical and useful, with geometric lines and bright colors. Plus, they're affordable. While they may not be quite as inexpensive as similar plain old metal products sold elsewhere, they're a lot more fun. We blogged their magnetic strip here. We have an orange one, and it really pops on the white wall of our office.
Three by Three's hooks, magnets, magnetic bulletin boards, magnetic picture frames, and desk and wall organizers all make it easy to change out, move around, and keep track of photos, cards, and all those other things that are so easily lost.
