Materials Needed:

1. Wood Circle or Shape: Many craft stores sell pre-cut wood circles and other shapes, or you can cut your own out of 1/8" thick wood or plywood. The diameter of the shape needs to be between about 3" to 3-1/2" wide to be able to hold a typical mug. The wood shape helps keep any moisture off of the table. You can skip the wood in lieu of another layer of felt.
2. Felt: Available at many craft or fabric stores. The felt is used to give color to the coaster, and also to hide the pad holding the essential oil. 
3. Battery Operated Diffuser Aroma Pad: These thin pads hold the essential oil inside the coaster.  These are available at most health food stores. (You do not have to have these pads and can skip that step and just put the oil drops on the felt.) You can also buy thick hemp or use another piece of felt.
4. Essential Oils: Used to give your coasters a unique aroma. About 3-5 drops are needed for each coaster, depending on how strong the aroma is.
5. Other Materials: Sharp fabric scissors (to cut the felt); glue (white school glue works well).

	Trace the wooden shape twice on a piece of felt. Cut out the shapes you traced on the felt.
	On the first felt shape, trace around the square Aroma Pad. Cut the square out of the felt shape.
	Spread glue over the entire top surface of the wood shape. Place the first felt shape and aroma pad on top of the wood shape and press down firmly.
	In the second felt shape, cut a small hole that will go over about the center of the aroma pad. Spread glue over the top of the first felt shape (do not put glue on the top of the aroma pad) and glue the second felt shape to the top of the first felt shape.
	Cut shapes out of different colored felt (or other material) to decorate your coaster (if desired). Glue your decorations onto the coaster. If you use one of the decorations to cover the small hole in the second felt shape, be sure to only glue it on one side. This will allow you to lift that decoration to access the aroma pad.
	Finish decorating with paint, markers, glitter, etc. To use the coaster, drip 6-10 drops of your desired essential oil or blend through the small hole onto the aroma pad, pausing between every few drops to allow the oil to soak into the aroma pad. Place a warm mug on the coaster to enhance the aroma. If the scent begins to fade after a while, recharge the aroma pad with a few more drops of oil.

 

Extra Ideas:

Make fun gifts by placing Aroma-Coasters in plastic bags along with 5/8 dram bottles of essential oils or blends to re-charge the coasters. Create a header-card to go on top with the scent used, and instructions on how to use the coasters. Include more information on other ways the included oils or blends can be used if desired. Create a gift-set with multiple coasters, mugs, and hot-drink mix in a gift basket. Note: Felt cutouts are available at most craft and Wal-Mart stores pre-cut with 6-12 kits per bag for those with little time
