I just got back from a two day basic marquetry class with Paul Schurch at his shop in Santa Barbara. The class was sponsored by my woodworking club.
It was an amazing experience, and it will take me several weeks to absorb all the information that was packed into my brain. He's got a very fast and accurate technique and does stunning work. He was very generous with his time (staying well after hours to help us all finish our projects), and is extremely patient (especially with my newbie mistakes).
My wife had chosen a peony flower as the project she wanted me to do during the class. It was an extremely challenging project for me, seeing as I had never worked with a scroll saw or veneer before, and am just starting my woodworking hobby. Nevertheless, she is thrilled with the results, and I may get a scroll saw and vacuum press in the future . She's already planning all the projects that will need veneering and/or marquetry.
If you have a chance to see him present a topic, or take a class with Paul, go for it. It will be worth it.
If I can, I'll post some pictures from the class.
