MMNN- Congrats on your first sale! Checking my Esty it appears that I had my first sale after a little over a week. Though, I had been selling for a while on EBay before that.
You can also get yourself out there by blogging, setting up a FB FanPage, and a twitter account. I also advertise on Craftcult. I think a top scrolling ad for specific Easter products would be great right about now.
You could also check out Project Wonderful for ad spots on blogs. Timothy Adam Designs has a good little tutorial/video to get you going.
