Sorry, was even a debate for me.. Cotton. The idea is to absorb, stiffen and seal. The debate for me was weave count and durability.
I used bedsheets on the interior to see how it worked and learned pretty quick I didn't want something that light duty on the exterior. I went to the HF Canvas for the exterior. Much better material for durability and happy I did so.
What I didn't know at that time is what Duck Cloth is and if bought on sale, comes real close in cost. Much better material in all aspects! IMHO
If you're in planning or working towards covering, start sourcing duck cloth and look for sales. Bedsheet the interior and save some $$, but exterior.. Duck Cloth!
