Fitman's Sampler is very nice looking packing puzzle. Great for a beginner but maybe not so easy for everyone. I did manage to solve this quickly but when I passed it along to several others, both puzzlers and non-puzzlers, I got greatly varying results. Overall I don't think it is difficult but it's still fun. Although this puzzle was easy for me to make, I did invest a good deal of time into making the box more attractive.
Two wood combinations: Chocolate; Chechen (pieces) and Walnut/Baltic Birch Plywood/Merbau (Box), Vanilla; Carob (pieces) and Maple/Baltic Birch Plywood (Box)
