If you’re trying to find a headband to attach your troll horns to, go to any dollar store or 5Below and buy a reindeer headband. I got mine for $1, (don’t buy a headband with super tall reindeer horns unless your cosplay calls for it. Get the shorter ones for trolls like Karkat or Terezi). Since they were already designed for reindeer, the headbands have metal attachments that were to hold up the horns. So get rid of all the reindeer paraphernalia and attach your troll horns to it instead!
