I am suspending my youngest son's bed from the ceiling via metal wires that are about 1/8th inch thick. It is going to look excellent! Let me describe briefly what I'm doing:
Each wire will be hung from a giant hook drilled into a crossbeam that holds up the ceiling. The other end will be passed through a hold drilled in the corner of the bedframe, perpendicular to the floor. What I need is some way to anchor the wire back to itself such that it can bear about 75lbs of weight and not be pulled back through the hole I plan to drill in the wooden frame. Also, I don't want it to look terrible - the solution needs to be nice and not leave a huge hunk of wire hanging down or whatever.
Perhaps this isn't the best way to go about it, and I should get one length of solid wire that will run from one hook, through the frame, under the bed, through the frame again, and back to the second hook? I'd rather not do this, as I already bought the wire but ran into the problem I described.
