We haven't got a tumble dryer - it takes about two days for the liners and wraps to dry after they've been washed, and will do a daily nappy wash. Will only wash the wraps if they're pooey/dirty, but not if the liner has caught it all.
So how many wraps am I likely to go through in three days?
Also can you really not use fabric softener on them? How do I uncrispify them?
