Because it's worth bragging about...
I totally did a 3000 piece puzzle. Yes, there are THREE zeros behind that, making it a THOUSAND not hundred. I am a puzzler. I love doing puzzles, and as my close friends and family will tell you, I will shame just about anybody with the speed at which I do my puzzles. I usually pound out a thousand piece in a few hours. But, thousand, to 1500 is just about where the puzzles kind of plateu... it's hard to find much bigger in a regular store, so to have had and finished a 3000 is pretty great! Thus, my bragging :)
So here you go, proof!
Time: FOREVER! No, but seriously, probably a good 30-40 hours, if not a few more.
Cost: FREE! Yay for hand-me-downs!
