We have a wooden mantle but I didn't want to put any nails in it to hang the stockings. I purchased these 3M hangers that stick onto the wood and when you want to remove them there is a way to stretch the sticky stuff to release it. Should not make any marks on the mantle.
I know you can purchase these heavy stocking holders but didn't want to spend that much plus I didn't want to take up the entire top of the mantle with 10 of these holders.
