Thanks fellas!
these pieces simply butt up against each other?
The sides or the veneers?
The sides are joined to the legs by having the panels tenon into the legs about 1/8" (routed slots in the leg sides) to form the basic box. upper and lower edges of the side panels are framed with some 1/2" wide x 1/4" thick walnut.
The sides of the lower drawer are held to the face with sliding dovetails, face is then framed with walnut.
The veneers are butted together on the contact paper to hold it all together, then the entire sheet is glued to a piece of BB plywood just like a solid sheet of veneer would be.
These geometric patterns are easy in that you can cut the straight edges with a paper cutter or knife using only a straight edge as a guide. The laser just makes the cuts fast and super accurate. I take a sit down and use tweezers to place the individual bits onto the contact paper. Takes about an hour per panel, but I'm careful to use single rows from the veneer so all the grain aligns up. If you don't do that, I doubt anyone would notice but I like to push it a bit.
