practice with thin card - like the big side of a cereal box - thats what I did. Although the card may not be easy to cut around the base of the dials , bear this in mind. When done correctly, using quality plastic backing card, you wont be able to tell the difference until you touch the plastic cover versus a laser cut alloy template - but then again the alloy is like x10 more expensive
