Thanks Top for the info. So, then what you are seeing is slightly heavier than what is used normally up there. We've tried heavier and finer material. The heavier, didn't work. It wasn't more lasting and it had less light transparency. The finer tore much easier so we settled with this thickness. We have to have it shipped by the the full roll. The rolls are 100 mts. long. One is amazed how fast one uses 100 mts...
and its always such a relief to have extra lining kept in the storeroom...
