From a buyers stand point, I love Etsy. It is where I go when I want something different. I check the site about every other day, if not daily. I also love it for inspiration. I have even bought fabric from there, all good experience. On another note, I do think sometimes prices are too high. Yes the item is adorable and I would love to have it but spending $100 + $15 shipping for something that I probably could do myself cheaper, no thank you. If you do sell on there, be sure it is priced right. Priced so you make a profit sure, but not so high that most won't buy it.
Best of luck to you!
