What is the best way to hang a styropor form?
The best way to hang a styropor form is by putting silicon glue on multiple screws and screwing these in the back the form. When the glue is dry, you can put some iron wire between the screws to hang the form and divide the weight over the whole work. Make sure to use screws with the correct length (not too short, but also not too long)! The larger the work, the more screws you should use: always hang the form on multiple hooks in the wall.
