These are extremely simple and cost effective! First, take a few drops of scented oil (can find Philosophy Amazing Grace fragrance oil at Save-On Crafts) and mix them with equal parts epsom and sea salts. Once you like the level of fragrance, the salts should be funneled into jars. You can get jars from the local craft store, but Save-On is a great resource for jars too! Once the salts are in their jars, add little hang tags. The above tags are made from madebyjackie on etsy, and were super affordable, but you could make stickers or tags at home too.
