Upus Juice Volume Affects


Exactly how much volume of material can you affect per dose of Upus Juice. One dose is required to make a ength of 100' of Rope of Dead Women's hair, but how much of it is required to treat cloth? If you wanted to make, for example, highly durable sails how much Upus Juice would you need? Anyone got any ideas?

Additionally, how much is Silk by the yard? D&D has it at 5Gp per square yard, so would Conan place the price at 5 Sp/yard^2?
