Hi, I've just made this for my grandson's birthday, he'll be 24 months old and has been diagnosed as 'autistic'.
I made the puzzle in ? in. BB, and it came out with a 'slant'...(I've read since on the problem); so I took my Dremel and re-faced all the joints, to eliminate slant, and was pleased with the result. Being only 2 years old, it will be easier for him to assemble it.
So this is it, my first 'official' piece.
