First knitted piece of clothing and next project

I just finished knitting a tank top. I think it turned out rather well. I used a cotton / acrylic blend yarn in blue. And I worked it on a size 8 circular needle. I had never used a circular before though I found it much easier on the wrists than straight needles.

I intend to start socks next, I just need to buy size three double pointed needles. I'm a little nervous about it since I will have to use stockinette stitch and when making short rows I'll have to do the purling. Which sucks because the stockinette stitch is my worst.
