I recently made a custom card set order featuring the name of the customers blog. The cards can be used as thank yous for orders or for corresponding (snail mail style) with other blog friends.
I had a lot of fun with this request and was happy for the chance to take out some time and be creative and original. The set featured six individual note cards made with papers from gcd Studio's "Loverly" collection and six hand stamped envelopes.
Also, I launched a store on ArtFire today;http://www.artfire.com/users/IndigoWings. I will be offering the same types of items as I am in my Etsy shop, handmade cards and paper crafting supplies. Two advantages to ArtFire that I have already discovered are that you can list your items absolutely free of cost and there is a direct button to twitter on the page with your listing. What that means is that as soon as you list your item you can easily jump over to twitter and post a link and a blurb about it. Although I haven't gotten any sales yet, I've already gotten nearly half as many hits in a day on ArtFire compared to the number of hits for the past month on Etsy. It's true what I've heard about Twitter--it's an amazing marketing tool--I will definitely be spending more time exploring that option and it's potential in the near future.
