Tank

Well, I think this will be my next project. I have several balls of Elann.Com Sock it to Me Collection Esprit. I cast on for Knitty's Honeymoon Cami only to find that the lace pattern was lost with this yarn's texture. So, today with a trip to the LYS I found this pattern from Plymouth Yarn Design Studio. This is a 2 piece pattern, but I would like to try to convert it to knit in the round. I have never converted a pattern before, I think the arm holes is what will throw me off.

Any suggestions for how to do this?
