I just got Instagram. I know, kind of late to the party. Find me: @thecraftyroach. I also had twitter, but deactivated it after about 5 minutes. I can only handle so much social networking.
Disclaimer: I'm keeping my Instagram private for now, just because I don't want to end up with a lot of spammy followers (I already got one and I haven't even had it a day!), but if all your photos are crafty related, I'll be sure to accept!
