When creating your graphics, you want the finished file to be as wide as the circumference of your rolling pin and as tall as the barrel.
A quick geometry refresher – the diameter is how wide the barrel of the rolling pin is if you measured from the two widest outside points across the barrel. The circumference is the length if you wrapped a tape measure around the outside of the barrel. You can easily find the circumference if you take the diameter measurement and multiply it by 3.14.
Remember that if you are using text, the image needs to be reversed so that the text looks backwards. This ensures that the text is read correctly when it is embossed in the dough.
When using high power for a deep laser engraving, make sure that the non-lasered parts of the barrel remain clean of soot and scorching by masking the entire rolling pin. You can use masking, application or or painters tape for this. Make sure that the tape is as even and bubble-free as possible.
Import the PDF file into Corel Draw, customise it or use your own design and send it to the laser. Make sure that you have activated the rotary attachment and entered the diameter of the rolling pin in the properties dialog.

Once the laser has finished, remove the rotary attachment and masking tape then inspect the rolling pin for smoke residue. A good scrubbing with a dish cloth and soap will make sure that all the dust in the engraving does not get in your dough. If the rolling pin is unfinished, any extra smoke residue left on the barrel can be lightly sanded off.
