People post from time to time about cheap suspensions so I'd thought I'd share this. This is not really new, just rearranged some old stuff differently. Borrowed from the hardware free detachable hammock system by grizz and it's essentially a copy of Dutch's whoopie hook suspension which is pretty popular around here.
Rather than using hooks there is an eye splice which ends in a diamond knot to make the connection to the continuous loops. The continuous loops have a slide-able whipping knot to securely cinch around the knot. Most people going for cheap suspensions are using all webbing. And almost everyone has thinner accessory cord. If you've got that you could pull off this with a single order of 25ft of amsteel from dutch for about $5.25. Gram weenies might also find this interesting as you could make a diamond knot stopper and whipped CL under a couple grams.
I don't plan on using this, I recently threw it on my wife's old hammock and whoopie slings. If there is a big demand I could throw together a video in a couple weeks maybe, but like I said, this is old hat for the most part. So here are links to everything you'd need to know:

How to make whoopie slings
Spliced eye - Start with about 10 inches of amsteel, connect it around the whoopie sling so you have two equal length tails and make sure it freely slides along the whoopie. You dont want it tight. Don't do the bury shown in the instructions, instead youre going to tie a diamond knot in them.

Continuous loops - I'd make them smaller
Slidable whipping knot - about 3:45 mark although viewing the whole video will probably be helpful, especially more details on the diamond knot stoppers.
