With regards to folding the mesh. Our stock answer is it is not recommended. But as I said I have lots of folded samples that may have been stored that way for several months from a previous trip and they stretch up fine. The folding could introduce some weak spots or slight wave in the weave is my take on it. For anyone wanting to try 225/S yellow we have a ton of samples we made up to give away. Hit me up with a PM and a UPS# and I'll get some out your way. They will ship rolled up.
