I'm having a major problem imagining what you are going to make. So I would need to know that, and see a picture of the pattern you say you have, before I could picture it in my mine. I'd likely have different ideas of how I would do it with that info. And if the holes are to be 1/2" deep I'd probably drill holes thru 1/2" material, then glue that to a solid piece of 1/2" material, or 1/4", 1/8", or whatever..

.....Call me a craftsman, artisan, or artistic, and I will accept that. Call me an artist and you will likely get a quite rude comment in return. I am not a @#$%ing artist.
