Unfortunately the samples of material that I have managed to get hold of are very small and I am unable to test them effectively. Rather than buy full metres separately I wondered whether anyone had any off cuts they would mind sending to me? (I would of course reimburse postage costs etc). I am looking at fabric to shield against wifi primarily so a high DB. The material I am hoping to get a large sample of initially is Silver Tulle, however if you have a particular type please message me here and I will look it up and see if it meets my criteria.
