Those industries ladies in the USA take them apart and make pillows or cushions by weaving the ribbions, sometimes with a whole special one in one corner.
Seems like a great idea to me, shame I'm utterly rubbish at arts n crafts.
I keep mine (only have about 30 or so) at my parents place since I live in a small flat with my BF while I'm studying and it will be a while until we have anywhere big enough for a lot of my stuff. I have a couple of 1sts and a couple of thirds and fourths but the other 23 are all seconds - which I find a bit of a spooky coincidence!
I reacently sorted all mine out, i gave the ones i was not keeping to a local RC. it is cheaper for them to have a new center put on the rosette then to buy brand new rosettes
