I just started making hoops. I really like the way they feel with water, however I bruise when I use the heavier ones. A lot of people seem to suggest adding padding to your tube. Does anyone have a method for this? I have added the insulation tape (going around the hoop-as you would any other tape, then putting vinyl over it and gaffer on the edges) to some of my lighter hoops, but I don't find this helps with preventing bruising. It does give the hoop better traction though. Should I apply the insulation on only the inside of the hoop?
