I have terry flat nappies (Canningvale) that I've been using for 3 years. They are very hard and the loops are all flat so it is very hard to use a snappi with them. We got a new (front loader) washing machine this year. I'm not sure what's making the nappies so hard - vinegar doesn't seem to help and I don't have a tumbledrier. Any ideas of how I can get my loops to fluff up?

thanks
