The turtle is an Alex Fox design. It is not the first time I have made layered projects; however, it is the largest I have ever made. I crossed a threshold. My wood glue did not have enough open time for me to get it on before it began to dry, and it came apart two times before I got it done. I attached the top layer with 3M77 spray adhesive. There was a little overspray to clean up, but that piece did not come apart.
