1 cup oatmeal (ground in processor or blender)
1/4 cup lavender flowers
1/2 cup dried herbs (mint, lemon verbena, chamomile--whatever you have that smells good.)
mix it all in a jar or bag and include a small muslin bag. You fill the muslin bag and hang it under the running water --I use it in the shower too. You can also let the bag float in the water or use it to wash with. Then just empty the muslin bag and let it dry--it can be reused.
