To put on bottles of tinted water, bookmarks or hang tags... Fantasy Magic Potion Labels II digital collage sheet by magicpug, $4.50
Fantasy Magic Potion Labels digital collage sheet 18 labels for decoupage witches brew supplies and more. $4.50, via Etsy.
I love this etsy seller (magicpug)'s labels because they're gorgeous and Halloween-y, without crossing the line into gross. I get that it's Halloween and we're pretending, but I can't actually bring myself to pour a glass of something labeled poison, swamp demon guts, etc.. Moon beams or Black Cat's Hiss, however? Spooky AND lovely.
