I wanted to try engraving and cutting at the same time when I was starting to use my xTool D1Pro, so I started with Skull styled coasters. (I bought the design of a skull) and then I wanted printed in coasters. At the end of the cut and engraving I finish the coasters with varnish so it gets a glossy finish and sealed. I really liked but I think it would worked better like a Wall Art or something like that.
First Design an image that you want to engrave in a Coaster
then you can engrave in a square or round coaster or approach the figure of the design that you want to engrave.
