I love jigsaws made by a company named Pintoo. The pieces are plastic and fit together with barely an atom between them. The finished puzzles look great and you could easily frame and display them.
I’ve bought a lot by this company and given several as gifts. I think 500 to 800 pieces is an ideal puzzle size, but recently I got a 2000 piece puzzle:
This is a lot of pieces, and all spread out barely fit on our table:
Pintoo puzzles lack flat edge pieces so making the border is much more difficult than in other puzzles. In this case, sorting the pieces and making the border took me over 4 hours!
Finishing the entire puzzle took me 24.5 hours over ten days!! Here’s an animation of the puzzle after each work session:
Its a lovely puzzle and was a lot of fun to assemble. But I think it’ll be a while before I tackle one of this size again!
