Give perspective to your walls by creating a relief decor . Various wallpapers, medium planks, undercoat, gun glue, headless nails and acrylic paint will be your allies for this achievement. Start by covering the support wall with underlayment. You can then cover it with a thickness of acrylic. To make the panels, cut the paper strips to the size of the medium boards and then cover them. Then fix them to the wall using headless nails. You can add several thicknesses of medium to give more depth to your walls.
