A gift for the mother in law who wants nothing
Short answer: Choose something soft for the home rather than something that has to fit. Towels, home clothing or bedding are personal without being too personal.
Personal without being private
Underwear is too private, a gadget too impersonal. Home textiles land in between. See bamboo homewear.
Quality is noticed daily
A soft towel is used every day. That is where the difference between good and cheap shows. See bamboo towels.
Home clothing is a safe route
Soft home clothing in a straightforward size is worn by almost everyone. See bamboo loungewear for women.
