Need is the mother of inventive, i could not buy one so i made it.
I could not find fiberglass windows screen where i live (as most of the diy mesh heads i've seen use), so as replace i came out with the idea of use a bag, see the pic, don't know how translate the name, but im shure you all know.
here is the bag and the rim
just before start sewing
work complete!, works like a charm and its really really resistent, silent and perfect bounce.
if you have a question just ask.
PD:sorry myu bad english
