I just recently added a few ad spaces here on AlteredStuff.com. The ads are thru Project Wonderful and the prices start at only 20 cents per day.
If you'd like to buy an ad, just simply click on one of the boxes in the left column that says YOUR AD HERE. You may have to register with Project Wonderful, but it's really simple to do... just follow the steps and you'll be on your way.
I'm just an email away if you need any help or have questions. ewenmeprintables [@] gmail (dot) com
