Heres a great Noah's Ark set I just finished and am quite happy with. The Ark is Poplar, various woods from the misc. scrap[?] box were used for the Animals and Mr. and Mrs. Noah. The thickness of the pieces except the ramp are 3/4" and 1/2" and I quite enjoyed sorting out the pieces to use for the Animals. This plan I bought with Steve's recent discount promotion with Toymakingplans.com. Enjoy my build
