Chanell, I hopped over here when you mentioned about the laundry basket - and, oh my word, those pictures of the mushrooms growing out from the laundry basket are fantastic!
The spare one I have is yellow, that wouldn't really be suitable, I think ... what I do have is an old wooden bedframe, the headboard and footboard could do much the same job as the laundry basket. Argh! I'm working on fixing my bathroom at the moment, its difficult to find the time to do the garden (and its still not advisable to walk on the grass too much, because its all so sodden).
The other thing I have, in relation to mushrooms, is a four feet long piece of silver birch tree trunk - you're supposed to drill holes into the wood to inoculate it with spawn, and just leave it to do its thing.
I love mushrooms so much
