One fun thing you can do on Etsy is make a "treasury" of items for sale on Etsy. Most people do a theme for these treasuries. I recently created one with a theme of "Where did June Gloom go? (I want some clouds and grey in that blue sky, it's just too dang HOT!)" and it made Etsy's front page! Here is a screen shot:
I really liked all the cloud items I found for sale! Here are upclose shots of the various items in my list in case you want to buy any.
