When you think to build a rope bed you have some questions…What size rope should I use?, How far apart should I place the holes?, How do I get the ropes tight enough so they don’t sag? .
What size rope should I use? The bigger the rope, the more you will feel each place the ropes cross (over and under). It will feel like a lump or a knot. I use 1/4″ sisal and have never had a problem with strength and it results in very small lumps.
(They are actually very comfy, like a hammock.)
