Hi, I'm building a weather balloon with some friends and we are wondering how we build the parachute. We have decided to build one using nylon instead of buying one. I have purchased 1m x 2m of parachute grade military nylon for about £3 but I haven't a clue how to build it. The best idea on how I have thought of is cutting it into a hexagon, cutting a hole in the top and attaching string to each corner, will this be sufficient? If not, how should I do it? Thanks in advance.
