Add instant texture, interest and dimension to your clay using these two impression mats. The 2 mats within this set will give you the look of cobblestones or a dry brick wall look. Great for adding texture to your mixed media or other home décor projects. To use the impression mats, firstly roll out some clay in in a colour of your choice, between 1mm and 2mm thick on a glass mat dusted with cornflour. Then take the mat and push the textured side into the clay. Lift the mat off and move it to extend the texture if desired. Leave the clay to dry and then use some gilding wax over the texture to help bring it to life!
