I have used scents in a bunch of mine. I've saved rose petals from our roses and added a bit of the rose oil to them and tossed them in the buckwheat bags. Also lavendar is very popular, so I use some dried lavendar flowers and also a bit of the oil. I've bought the oils from our health food store, from Michaels and Joanns. You can mix crushed cloves, nutmeg, cinammon, etc. or even cut up vanilla beans. Whatever makes you happy :) :):) Its one way to clean out your spice cupboard hahahaa.
