I've been spending some time on Etsy these days since I set up my Vintage shop there. They have quite a fun little creative community and if you are a creative sort, I highly recommend you check it out.
You can keep track of items you like and make collections of similar types of things: Home decor, clothing, wall art, jewelry, etc. You can also make little creative collections called treasuries. This is where I've been spending a great deal (too much) time lately. I've found it addictive. I collect related items and arrange them in a 4 X 4 grid of thumbnails for others to view and comment on. The items can be related by just about any theme you could think of, and I like to use a limited color pallet as well. Here is one of my most recent:
If you want to see more of them, just make sure you comment to let me know you stopped by!
