I was totally into puzzles when I was a kid. My interest gradually dwindled until I tried doing another when I was 14. Then my cat totally wrecked the thing before I finished, and I haven't done one since. Though recently I've had the urge to take it up again as a hobby, but I'm broke and puzzles cost money.
I used to do a couple of Jigsaw Puzzles by myself when I was Young.
I think I remember doing a 200-Piece Power Ranger Puzzle & The Lion King 100 piece puzzle. They would take me about a week to finish because there was always a couple distractions and errands to do.
And 2 years ago for Christmas; I got a Disney-Globe Puzzle
It had all the Disney & Pixar characters and the shape of the pieces were bent and would form a Globe that came with a Stand. I glued all the pieces together and it took me 2 weeks to get it together.
But I placed it on top of my Closet and it somehow/magically fell and broke; so I decided to give to my Nephews to try and build it.
