Cheese cloth ?? fishing site not cooking...just joking. If your using this to put trout or salmon eggs in, there are many places to get them. First off try your local tackle shop. Most maline cloths look like scarf's in many colors. Scarf's that are very thin also work (ask your mom or wife before swiping it). Other options are premade peices that are cut out in squares ready to put your trout or salmon eggs in.....once on the square use spider thread to tie off the end.(keeps the eggs inside).
hope this helps
