Step 1: To Make
Mixture is roughly 50/50 saw dust and candle wax. I used a variety of candles I found around my home and sawdust from my guitar shop.
Heat wax. Careful not to catch it on fire. I do this outside for a reason.
Mix in saw dust.
Let cool to the touch but not to solid.
Lay out coffee filters and put mixture into middle.
Roll them upp tight. Wax should soak thru the filter.
Let them sit for a few hours.
