I don’t use bar soap but I also don’t like throwing out soap bars that sometimes come my way. One day I noticed how nice one of the bars smelled and so I unwrapped it and placed in in my linen cupboard. Within hours my linens had picked up the scent from the soap bar. Nice!
Tip: don’t place unwrapped soap directly in contact with your towels. The towels’ nap picks up particles of soap which will rub off on your skin when using them after showering.
