Leaf with in a leaf pattern in an oval frame. Cardboard stencil with leaf pattern and oval frame
I used water to make it stick - try any type of glue that is not on the cardboard/leaf on the visible side
Make sure that the pattern and the oval are on the same place and to not remove the cardboard from it's original position (or mark the position and before starting the first engraving)
Engrave the oval (left - blue) on everythign
Remove the leaf and engrave the pattern (on the right)
