I have two hammocks: a smallish nylon hammock (for camping) and a largish cotton one (for the rest of the time) and I got a question the other day that I hadn't considered: how do you wash it? Is nylon machine washible? Will either one shrink? How can I keep the strings from tangling in the wash? (they're both brazillian hammocks and have strings occupying the last few feet of their length) and if machine washing is out of the question, what do I do then?
