I found this super-cute little tin washing machine (it's supposed to be for keeping your washing powder in)
and this washing-machine laundry hamper (which we are using as a dress-up box) at Tchibo (my favourite store, by the way).
I also bought myself a new laundry drying rack with clips, which Princess Pea immediately claimed for her play laundry!
She's been putting her clothes into the tin washing machine, pretending to add detergent with the scoop that came with the tin, pressing the 'buttons' to get it started, then taking it all out and hanging it up to dry.
She also loves to help hang up the real laundry, and can spend ages sorting and resorting the laundry clips - a fun activity in itself (also good for math skills - counting and sorting - as well as small motor skills!).
