I did some ad swaps recently. You can see new ads on the right side of this page. I swapped with
Eyelah, Foxy Whispers, ElizaK Prints, Twigs and Tea and Artsy Ants.
If you want to do an ad swap with me, email me and let me know. The sizes are 250 x 125 or 125 x 125 pixels. Just let me know what size ad you need for your blog. If you would prefer to pay to have your ad up, you can do that too. I changed the prices a little and added some new info in the Advertise section.
Speaking of ads, I made a couple ads just for my blog. Let me know what you think.
If you have a shop or blog, do you do advertising? What do you find effective?
