Very Nice! I got the yellowheart that I used for my Catan Board (Here), on Amazon.
This one looks like it might be a good fit.
It doesn’t look like they have the project boards that I originally purchased. I got pieces that were 3" wide x 24" long x 1/4" thick. There were 3 Yellowheart, 3 Purpleheart, and 3 Bubinga pieces in the pack. The unfortunate thing was that the original Catan Resources are just a smidge over 3 inches wide, so I had to scale the entire thing down by about .25". In the end it wasn’t too noticeable, but it introduced a LOT of additional work.
