I don’t have a tumble dryer but Carmen does! People sometimes post on the internet about zapping felt in a tumble dryer for a short while but this is not something that I have ever done myself. Anyway, Carmen was telling me that she tried it out for the first time the other day and put a rug in her dryer for approx 10 minutes and it worked out amazingly well. I would be really interested to get any comments and feedback from those of you who have tried this out before, did it work, was it a disaster, would you do it again???
