walk around the room a few times very close to the wall until you are confident that you have your balance sorted, after a few laps try a couple of laps walking around with your hawk and trowel in your hands, when your happy with that do a few with your hands in the air (always keeping close to the walls just in case), 20-30 minutes of this and you should be fine. these tools are a godsend, ive had mine for ten years and have earned a hell of a lot more using them than if id had to deck out all the time. DONT TRY TO BE CLEVER, get all leads out of the way and dont walk over dust sheets, put all the tools you need up on your spot board (hawk/trowel/paddlebrush,scrim/knife/bucket of water etc), get it on and think of the lolly, you'll soon luv em
