To be honest, I have absolutely no idea about the differences between "CN" and "CT".
My source (I live in Finland) is a German based extremtextil, they sell three different varieties of cuben laminates (multiple colors) and the 3M adhesive transfer tape by the roll: http://www.extremtextil.de/catalog/a...keywords=cuben
They have an amazing selection of DIY materials and they ship worldwide, but given the current EUR vs. USD exchange rates the prices are probably absurdly high for US-based customers. Oh, and I believe you can even order quantities of less than one meter.
I have only about one meter of each material left, so I cannot do anything too fancy with those. Maybe I'll get some more and try making a pack... or rain chaps... or a rain poncho... or...
