To Create the Yoga Block Outline: Scan the yoga block and bring it into your graphic design software. Create an outline around the yoga block for the laser to follow using your software's pen tool. With the lid of your laser open and Red Dot Pointer turned on, send the vector outline to the laser and adjust your yoga block's positioning on the engraving table.
This will give you a visual indicator of where the design will engrave - adjust the template accordingly for each yoga block. When you're happy with the placement, send the raster job over.
