You can handle the mat as a whole or cut out small areas of the mat. By spray glue "Haftfix" (Item No. 61151), the grass mat can easily stick. If you want to stick the grass mat as a whole or in large pieces on a flat surface, you water the mat previously slightly, for example, with a water vaporiser. So you prevent curling after drying. The used glue on the mat is water soluble. If you carefully damp the grass with a brush, you can scrape the fibers off after a few minutes and create as streams and routes.
