So I just got my machine yesterday, grabbed a couple images from the store here and for my first project I made the attached "sign" as a test. I think it came out amazingly well (watching all the videos I did was a big help).

My question is this - what I'd really like to be able to do is layer boards, like with a dark walnut on top of a lighter wood below (say, maple or even pine). This way the tops of the lettering and designs would be highlighted and the depth would be lighter.

That said, in order to do this I would need to glue-up the boards...which I'm fine with but I noticed on the product page for the bits that one of the main things that cause the bits to dull faster. Have you folks experienced this, and if so is it still worth it for the effect or do they dull so fast it's just not worth doing it this way?

Any/all advice on this technique would be welcome!

Thanks ahead of time for your help.
