I found an other free advertising website recently. It's called the Banner Homepage. You upload a 125x125 banner (the same size as Project Wonderful) and once it's accepted, it is shown automatically. Right now, it is pretty much taken over by money making websites... I think both of my blogs are the only exceptions to that.
This is where YOU come in! I would LOVE to see more DIY/Etsy related banners up there.
Please blog about this! Post your banners! I want all of you to get more free exposure!
