i like the nylon filter cloth, because i always have it on hand, either will work well. another method, easy, is to use the dish towel/sack cloth, or a thread bare t shirt but add a piece of paper towel (bounty) on top of the dish towel/t-shirt. (you don't need a whole paper towel, just enough to pour the wax through, enough coverage so that the wax melts through both materials; a smaller square). make sure when you remelt and filter, pour the wax slowly so that the paper towel catches the remaining sediment. you can remelt and filter into one container, keep that container warm or reheat and then pour into whatever mold you were using. some beeks have used coffee filters for this in lieu of paper towel, not sure how well this works?
