Puzzle pieces

I got this in the xmas parcel from our daughter. The puzzle is 3D and round, so it ends up as an ornament for the tree (see extra). I'm going to try to get a start on it today. I remember doing one like it with the girls a few years ago. We used to do puzzles every Christmas, usually me, our daughter and two granddaughters. The granddaughters usually lost interest and our daughter and I would end up finishing it, often staying up late the night before G and I left to come home. Good memories.
The pieces are numbered and I seem to remember that getting the puzzle started was the hardest part. I'll blip the finished ball sometime before next Christmas.  :-))
