That is the method we also use with my nieces, in a huge piece of cardboard, on the floor doing puzzles, but we didn't put it away until we were done - even if it would take weeks (or months 😂)
Imagine the scene with a cat and a long-haired dog around that sometimes entered that room. A disaster hahaha
🤣🤣🤣 well, I put it away carefully under the bed because it was a huge puzzle and sometimes I got bored or had to study so I didn't have much time to finished it in just one day or weekend 🥴 hehehe. In fact, that puzzle took me weeks to finish it 😬🥴🤣🤣🤣🤣🤷🏻♀️
Hahaha, with cats or dogs around must be fun to try to make a puzzle 🤭🤭🤭. I only have two small puzzles now that I use to make for fun and then I put them again in their boxes. Maybe I should buy some big ones 🤔 it's a fun hobby.
Btw, those 3D puzzles you have are amazing, it must be more difficult to put them together
