I am into jigsaw puzzles. I'm picky about them, though. So, trading doesn't seem that likely. I do have one that I'd be willing to trade, though:Mona Lisa 1000 Piece Puzzle
-- I basically found this one too hard. The background and darker parts gave little to work with. http://i.imgur.com/FOnAJWY.jpg
as far as I got with it before I gave up.
I'm mostly interested in 1000 piece puzzles that have a picture I like and a decent amount of differentiation in the image so that they are doable visually. These tend to take me about 2 weeks which is good for me.Greg Hildebrandt - Smaug Dragon
is one of my favorites. I plan to do it again in a few years.
p.s. Here's the one I'm working on at the moment: http://i.imgur.com/5RSTx2w.jpg Diego Rivera: Detroit Industry 1000-Piece Jigsaw Puzzle
- it's somewhat challenging, but the pieces have a lot of details to work with.
