In this video, I used 200 feet of 1/4" rope and a strong-but-lightweight frame I built with four sections of 3"-diameter PVC pipe from a hardware store. (You can use larger PVC pipe or wood.
Materials Needed (as shown):
(Metric conversions shown on video.)
4 7-foot lengths of 3-inch PVC pipe
4 3-inch PVC pipe elbow joints
20 3/8"-diameter x 3-inch long eye bolts
4 3/8"-diameter x 4-inch long eye bolts (for elbow joints)
24 washers, 1&1/2"-diameter with a 3/8" hole
24 locking nuts (with the plastic liners)
PVC pipe cement (if you cement an elbow to each pipe, you can disassemble your frame)
Rope: two 50-foot lengths and one 100' length of 1/4-inch solid braid cotton sash cord (clothesline)
Power drill with 3/8"-bit
This piece requires about two hours to tie.
