Great job Stephen! Way to stick to it and not give up! You give way too much credit to me. It was all your doing. Congratulations! It is not only a testament to your woodworking skill, but also your patience! 180 pieces!! WOW!! Truly an amazing accomplishment.

So you said you'll have 100 of those ready as your exchange puzzle next year?
