Before I started shuffling around the country I flat-out refused to join social networking sites. But, as I met more people I met and wanted to keep in contact with, I realised it was going to be a necessary evil in my life & now I can't live without it. But I TOTALLY understand not wanting a personal profile.
What you might want to consider, though, is that your reluctance the join facebook, knowing good and well that everyone and their mothers on it, could be costing you exposure. There's no reason you can't open a personal profile under a false name JUST so you can have a business page to offer to the members of facebook. On the business page, you'll be able to put up picture albums of your work, send pictures and links to whoever your heart desires, and promote your Etsy shop- which, by the way can be attached directly to your facebook business page :)
Don't cheat yourself. Treat yourself!!! Feel free to take a peek at my business page. Notice my real nem doesn't come up unless I want it to because the page isn't about me- it's about promoting my product. Good luck!!!
