Should have also said i line the lower cupboards to stop other items sliding about.Lindsay,
I line all the overhead storage cupboards with the non slip rubber which you can buy on a roll from caravan shops or Lakeland Plastics. In the overhead cupboard of our Swift Conqueror which holds the cups and crockery it stops any movement of the cups etc. As a result i have never had anything falling out of a top cupboard. I make sure that the plates, bowls are a tight fit in the racks.
