I quit buying Christmas presents a few year back. I was always notorious for being cheap and waiting until the last minute (both of those things are pretty true in my life in general). But if that describes your approach to shopping, you are in luck because there are lots of deals out there and you have plenty of time.
A New Playground (2010) by Shaun Kardinal
Daily Candy has a list of things you can find in SOIL's Gift Shop (which is a part of this) - prices start at a dollar. Matt Offenbacher's postcards ($1) would make a great holiday card. Get organized with a Vs. The Matador calendar ($25). I really love Shaun Kardinal's embroidered pieces and the etched bottles by Kristin Ramirez. Swing by Wednesday or Thursday (from noon to 5) to get all your last minute holiday gifts.
Bear Brooch (2010) by Maki Tamura
If you have a little more money to spend you might like these brooches ($250) by Maki Tamura available at Open Satellite.
Or email an artist you like (or their gallery) directly with your price range and see what they might have available.
