I think I would like to make bath salts for Christmas gifts for co-workers and friends. So I can get the baking soda, food coloring and epsolm salts at Walmart. Friends said go to dollar store for glasses, and Home Depot for the cork if the glasses do not have lids or toppers.
but where do I get essential oil [the type that can come in contact with skin] and glyercin – if I decide to add?
I have found recipes online for mixing the batches.
