I was amazed at the variety of guesses, everything from 100 to 2555, and I was so happy to have so many play along. Many thanks to all of you for reading my little blog! The actual number of buttons in the jar is 1734. The winning guess is
1758 from DeeDee at
DeeDees Craft Spot. Send me your address, DeeDee, and I will get your altoid tin of buttons in the mail!
