Help I think iv ruined my work!!!

[Maxitaxi]

Hi,
I'm knitting lots of different squares for my blanket and a lot of them were all curled up when is finished so I got them all and pinned them to a damp towel and put another damp towel over them. Then I pressed them lightly with the iron. Pulled the towel off and they are all flat and limp with no bounce or Life in them!!! I freaked out and thought to Hand wash them to bring them back to life but that didn't make much difference! I'm really gutted as I'm a new knitter and these took a lot of time!!!
Suggestions anyone please!
