Fair Isle in the round - is it possible?

I have been trying a hat pattern with fair isle in the round. I’m having a hard time with the carried yarns moving from round to round. Any suggestions for making this neat?

Fair Isle is BEST done in the round. It’s too much hassle to do it flat. it just takes practice to make sure the floats are loose enough so it doesn’t pucker. Here’s a video that helps a lot.
