Put the crystals in a sachet set them in a drawer, hang them in the closet and hang them in the car. Put them in jars and set them anywhere. Take the lid off and smell the wonderful aroma. You can get creative with the crystals by adding them to potpourri, the bottom of your trash can, set your makeup brush handles in them, put fake flowers in the sachet and then put that into a small flower pot. Put fake flowers in the jar with the crystals. The flower ends up smelling like the scent in the crystals. If you want that to happen a bit faster put plastic wrap or cellophane around the flowers and sachet and/or jar for a few days. When you unwrap it the flower smells like the scent. You can put a small amount in a sachet and put it in the filter part of your vacuum. Great for a small bathroom too.
Pick the scent of aroma crystal you want then pick the sachet bag or jar you want to put them in. We put about 2 cubic inches of aroma crystals in the sachet. We put about 3 cubic inches of aroma crystals in the jar. The jar will not be full. It can last up to six months. Not for the bath. Do not eat.
