After watching one of Steve's videos about cutting out patterns I had a few questions.

One of my questions is for a project that would be carving pendants from 1/4" to 1/8" stock.

Can I just stick random size/shape pieces to the carrier board using 2 sided tape?
or....do I need to stick on same thickness pieces like rails along the edges?
or....do I need to make the whole carrier board surface the same height without gaps between pieces to be carved? (like a window where the piece to be carved is set inside the opening)

Any input or links to videos will be greatly appreciated.
Thanks, Mark

I am new to this and have just been watching tutorials so far.
My machine and accessories will be arriving shortly. I also have all of the software and add ons.
Just need to learn how to use everything.
