Some examples from a recent exhibition I installed.
Screw eyes are bad, made worse by wireing around the eye, so physics can have it's say, and leverage can pull that screw eye right out. Bending, then pull-out, followed by crashing. If one insists on using outmoded tech, at least run the wire through the eye, around the shank, then back out the eye, then wrapping.
Now the staples, well, they were actually solid, at least until the staples start to loosen as the wood ages and shrinks.
Personally, cup holders are never going to be a good choice. This particular frame is relatively heavy, and the cup holder is already bending from the strain. Soon, the fall.
Solutions, next post.
