You can find spell jar recipes on Pinterest, TikTok and YouTube!
Also you don't have to put them in a jar, empty chapstick containers work, plastic bags, empty toilet paper rolls(not kidding), really anything that can close up and hold a lot!
Also also you don't need to pour wax over the jar or whatever, it helps if you do but otherwise you can just put the color of the wad into the container or thing or seal it with a ribbon of that color.
