Stamping is not only for children, but we can feel sometimes as a child when we use this technique.
To perform this technique you can use pre-designed stamps.
You can create stamps from styrofoam, wood or eraser.
Or you can use everyday's creatively objects as stamps.
For example, fruit, leaves, vegetables, etc.
Make sure the surface is clean, push the stamp in the paint and work your way around with the stamp, and go wild!
