Air dry your clothes for less rumble in the tumble (dryer). Your items rub against each other in the tumble dryer and releasing fibres that cause bobbling. It’s a more environmentally friendly way to dry your clothes, but also friendlier on your electricity bill. However, if you prefer to use a tumble dryer, why not try air drying your laundry for a while first, and then finishing it off in the tumble dryer.
