@Jitensha that’s a really good point! And it reminds me of fiberglass insulation, that is made of microscopic threads of glass. Touch it and it can seriously irritate the skin, making it red and itchy. A giant might itch a little afterwards if anything 😆
I am a firm user of terrariums and dollhouses, anything else is temporary like cages or shoeboxes or dresser drawers for sleeping in. I like my tiny lady near me otherwise when possible in pocket(with a protective lining) or riding my shoulder(maybe with a saddle).
