Many of my records got damaged by using nails to rest them on. Besides they fell off.
I made these small hooks so the records stay in place. The nice thing is that the arms from the one record on top are also keeping the record below from tipping. And because the hooks are a bit flexible I can easily press down the record, releasing it from the top to get it out of the wall of records.
I made them small to save material and to not see them too much when the records are resting on them.
