It is a technique that I've seen in Blogs Spain and Italy. It is working on a special sheet of styrofoam. The same stalls with a knife following a design. Each resulting piece is covered with fabric, to form a complete design.
I just learn the technique. I adapted it to the materials that had at home, because in my country is not known. I did a small clock for my sewing room. I present many photos, some of the step and the final result that already looks on my wall.
You pass a beautiful weekend!
A strong hug!
