Everyone was offering really good suggestions, the color changing charm a personal favorite since Evan did have schemes he preferred to stay with. He briefly felt like there was a Christmas conjuring spell specifically used in years previous to decorate the Great Hall but... considering he couldn't remember the incantation and was not 100% positive he wasn't just creating something in his head, he opted for a different one instead. Raising his hand, he waited to be called on before offering his own answer. "Epoximise can be used to bond items together. So if you needed a spell to use in order to create a popcorn garland or string of lights or even just to create long lines of ornaments, that would be a good one."

Especially in tandem with other spells already offered.
