Check your local hardware store for the small sheets of felt material with adhesive on one side you can cut out to stick on the back of drawer and cabinet edges to cushion their closing against the surrounding woodwork, also used under things to protect flooring. The soft side of velcro might be a better idea and may be thinner.
