Numerous customers who bought the manufacturer-made tent footprint for the 'Big Agnes Copper Spur UL2' tent reported on Amazon that the tent footprint is poorly made and NOT AT ALL a good purchase. The footprint is highly useful to convert the tent into a tarp-tent among other things.
I'm not sure what alternative footprint products are available to buy from the market (with the possibility of slightly altering it a bit myself to make it suit the tent). But if not possible, I'm considering making one myself. How does one go about doing this?
