I'll affix enough pins to ensure your heart rock pins nicely to whatever it is you want to pin it to.
Small hearts willost likely require a single pin, whereas larger ones may require two. I'll message you if I don't think the heart rock is compatible with the pin option.
If you're a particularly picky human, email me to request a brass, black, copper, or gunmetal gray pin. Otherwise, I'll most likely use these silver ones.
If you want to do this yourself, I recommend using e6000 glue. Apply a drop to the pin, let it sit for a minute, or until the glue gets a little tacky, and then hold it in place on the rock for 30-seconds.
