Those little sealable plastic bags that you can write on that are ideally suited for your metal detecting finds.
Handcloths, as opposed to dishcloths. One is for wiping yer hands, the other is for drying the dishes. Never the twain should meet unless yer a filthy durty ****. China cups/saucers/mugs/plates are the only kind of crockery to own. The higher the 'china' content in yer crockery the easier they are to clean and the less they stain. Re-sealable washable bags are a boon to anyone who cooks their ain dinner. Bookends are very handy if you have books.
Babywipes. They are fantastic for wiping your adult arse - I've no idea why they don't promote them as such.
They are excellent for a refreshing final wipe. Just don't mistake them for a Dettol Power Wipe. Very nippy.
