I have found that the first 3 rounds are the hardest. Once I get going, I am ok. I used size 8s on a scarf (before I got my Addi 16" circs) and found it very difficult. I had to start over several times. I just made a tiny sweater for my son's toy racoon on size 2 dpns and had very little problems...after the first 3 rows, that is. I only had to start over twice.
Practice, practice, practice.
