I use a carpenter's tool belt with multiple pouches. Mine has two large and two small pouches as well as a holder that contains my pen, magic marker, and paint stick. One pouch is used to hold a small can of red paint and a small can of green paint (I always run out of red paint first). The other large pouch holds my note pad. The smaller pouches hold my gages and mirrors. I also have a pair of carpenter's suspenders hooked to the belt to support the weight.
Good luck - Al
