If they've got a bit of stretch, you could use them as melon nets for holding any climbing melons. If they're not stretchy, or are too small, I reckon line 'em with a bit of moss or basket liner, fill with small patio trailing plants like those lovely heavily scented petunias (priscilla?) and some trailing toms and hang them on strong pegs on along a line (washing line, thin cable) between two uprights. Or attach each one at different heights along a fence. Either way, an unusual and lovely display.
