i use computer paper coated with a THIN coat of gorrila glue, then wrap it around a highlighter to keep its roundness, the staple it/tape it together so it can dry over night

but make sure u wear gloves becuase if u get any gorrila glue on your hands it will have a rough irritation residue on the surface of your hands

remember, a thin cot, dont drench it, i try to scrape as much off after about half an hour of the glue soaking in the paper. and remember a drop does alot
