Remember Weare by Moving Brands? That was a great idea. Annoyingly I seem to have lost mine. Wish I could order another. I always like it when the web gets squeezed into fabric.
And here are two really good examples which would make ace Christmas presents.
First there's the Tweet Towel from We Are What We Do. A tea-towel with a tweet embroidered on it. Obviously.
Second there are the Pistil SF map/blankets - blankets with lovely maps of your area (or wherever you like) on them. Designed by Stamen/OpenStreetMaps/Cloudmade. Splendid.
