Hi all. Has anyone ever seen the ballast bags used on the skirts of awnings to keep them in place. They are made of heavy duty clear plastic with a seal which means you can fill with water when required and then empty out when you are packing up. I first seen them on a visit to Forfar and went to speak to the owner the next morning and of course he had moved on...typical..... I have asked at various shows and shops but although some had heard of them nobody knows of a supplier. Any help would be great.
