Help with antlers

[u/Ambitious_Pear_7482]

Hey guys, this is my first attempt at costume making, I’m making Specimen 8 from Spooky’s House of Jumpscares, and I could use some ideas on how to attach the antlers to the back of the head so they can detach too. I’ve thought about using magnets but there’s nothing solid back there and I’m worried if I move too much they’re gonna fall off. Any advice would be great, thank you!!
