Here are 3 things you can put the Halloween potion labels on; jar, bottle, and can. For the Halloween season, the potion is not always good for your health. What if it was cooked by a wicked witch of Halloween?
The jar is the one that the witch mostly uses for pouring in the potion because it is larger than a bottle. The bottle is for the ingredients of the potion. You can't carelessly mix one base material with the others. While if there's no bottle left, the witch uses the can that they can seal it properly.
You can write the names of materials based on the witch secret potion ingredient. For instance, a poison, frog tongue, snake venom, snail saliva, and many more. See, you can also write the ready ones and the separated ingredients for the potion, such as 'an essence of fear' and 'witch brew.' On the label, too, you can write each of the ingredients, so that you know what other parts you can add up. Some substances can explode if the portion is not balanced toward each other.
Obviously, you need a piece of paper, ideally sticker paper. Another substitution is cardstock. All you need is to make a hole with a hole puncher and a felt to tie on the neck of the containers.
For the usage, you can put the potion bottles with the labels for decor, roleplay properties, mysterious gifts, and so on. Just follow these steps on how to get it ready.
Most of the inspirations of the color and design are from fictional worlds in movies, games, and novels about witchcraft and sci-fi. The labels are based on the current art and trends in the world's setting, usually classic and vintage.
Whereas in the real world, the practice of making Halloween potions could be secretive. Have you searched in museums for witchcraft and supernatural being? After all, you can just see how your mom writes labels for the seasonings for the kitchen necessities. You might as well see the gift tags and what it is really for.
