I always think of knitting in the round on DPN's like a clockface. You want to be working on your needles at the 6 o'clock position. You are pushing the stitches from the 7 o'clock position to the right to be knit. After they are knit they are on the right hand needle and you move them toward the 5 o'clock position. This will keep the right side/public side of your knitting on the outside. MerigoldinWA
is right, either way works just fine and it's up to you to figure out the way that you are most comfortable knitting to produce a finished project you like.
