Method of cutting out duplicate cards
Place a ruler in the center of the drawing card (10 cm) and cut a light line for the center fold along the ruler. (you can do this with a dull knife) You now have a double card with a left and a right side.
On the left side of your duplicate card, create the Tancart drawing with your original Tancart mold.
Place the ruler in the middle of the left side of the double card (5 cm) and cut a light line for the fold along the ruler on the empty edges. (do not cut on the places where you made the TanCart drawing)
Cut out the TanCart drawing with a Stanley knife, right up to the middle edge you made in the left side of your double card.
Gently unfold the cut piece, making the crease in the center of the left side of the folded card.
Make the fold in the middle of the double card and you have made a beautiful Tancart!
