There is this great company called Sticker Robot and right now they are doing a S.A.S.E giveaway- Self Addressed Stamped Envelope (if you didn’t know). Basically you go crazy and decorate on an envelope, send it to:

Sticker Robot
PO Box 1189
Woodacre, CA. 94973

And they send you back a bunch of stickers!! I sent one in, it was nothing fancy cause, well, my art skills are not that great.  But seems like they liked it – check it out here. There are a bunch of others there as well.
