YEA! Putting your art on things is a great way to go!

I use this company my self:

(Yea that is my affiliate link with them).

I like them, as you can integrate with Amazon, ebay, and wordpress, esty. So, you can upload your image, Then publish to 4 platforms. When the sales come in, they just send them out. I find just by amazon and esty I can sell more then trying to promote it myself. In the process of writing a how to guide about this. :D

In any case, cool pants!
