To make your chalk bag you'll need your favorite puppet or golf club head cover and a bunch of felty material. The material I used was left over and found in our scrap materials bin. You'll want something a little nappier than suede but not quite as nappy as felt. It should hold the chalk in the bag but not absorb all the chalk, feel the inside of a store bought chalk bag if you're really stuck. You'll need about a yard per bag unless you are a super high efficiency cutter. You'll also need a length of string and a little clamp end to tighten the string like a draw string. For the puppet just try not to pick something too bulky as you'll be carrying it when you climb.
