Advertising my etsy site

I have been looking for ways to advertise my Etsy site and I have found some great ideas. First is business cards. I put several in every package I send, and give them out to everyone. I also made flyers on my computer that say buy handmade and list my site with pictures. These go out in every package I mail also. Plus I ordered a return address label and stamp every letter and package several times. Stickers are good too. They can go on every piece of outgoing mail. Even bills I mail get stamped or stickered or business cards. I figure that lots of people handle the mail so why not do some advertising. I bought a bumper sticker for my car. If someone behind me then they will see it. I want to make t-shirts with beautiful pictures on them and my etsy site. The latest thing I learned about was the showcase on Etsy. Basically it's advertising in the different categories on Etsy. Some of them are hard to get, and you have to check back often. I did get one on the Storque page and I am going to list more blank books and get a spot on the books and zines. I'm sure there are lots more ideas, but this is what I've found so far.
