I received an order of cuben fiber today. 9.8 yards x 48 inch weighs 9.6 oz. I could have an 8x14 tarp at about 10 oz. This was my splurge. I sold some gear I was not using to get this. I am trying to decide whether to make basic rectangle, a copy of the Cat tarps, or a SG/JRB style. Some articles I have read say that the cuben fiber does not stretch like ripstop so the cat cut is not as critical. Any experience working with cuben would be appreciated.
