Latex

Rubber milk can be used for many projects and on many surfaces such as leather, fabric, knitwear, lining, cardboard, and paper. 

It's brilliant to make things non-slip. For example, you can smear or dab it under carpets, socks, and slippers so that you do not fall. 

Once the rubber milk has dried, it can be washed at a maximum of 30°C in the washing machine.
