Hi Johnno, thank you and others for the appreciation. I would like to test the tear strength of the fabrics. But I don't like the standard cut-then-pull-apart method as suggested by Franco. It is great for riping straight grain edges in the sewing room, but this is not what our MYOG tents are subjected to with any care while out camping. Sensible designs, with an appropriate attachment of guy-out, peg-out and pole connections that don't create bad stress concentrations to individual fabric fibres should suffice. I think we are mainly interested in preventing the start of a large tear in the first place. In my experience, a short tear is just an inconvenience and will not 'run' even with the loading of a howling wind. Do you have any good ideas for more sensible testing of this attribute? I'll capture some more bird songs for you if you can help. I'll catch them for you anyway as they just break out into song usually when the weather is unstable and I just can't resist recording. Tim
