I hope that this cheap and effective tip will be helpful to some. Using various cloths for screening, including nylon underwear is a hassle.
One can look up <silk screen materials yourtown, yourstate> I found two cloths of 200 and 300 threads oer inch. A single layer works very well. It was only about $5 a yard (and 4 feet wide.) I have used it in the past and it is great stuff.
It is a polyester of some kind. There is no fuzz between the lines, and you need a very good pair of eyes to see the holes. (Years ago, it seemed like some I bought was nylon filiment.)
