Just followed you on Tumblr! That wood necklace is beautiful! I don't know that I have any hints or tips for Tumblr since I haven't had one for that long. I just post any new items that I have on Etsy in addition to any craft/random things that I like (I reblog people). I don't know if it's really drawing any people to my shop as of yet, but it's definitely fun!
