Once he's done he loves to carry the buttons around in a Tupperware container. He has created other activities, such as naming the buttons, counting them, lining them up, and singing songs about them! We've got buttons on our mind!
We used buttons that Nana has collected over the years, but I would love to buy this Chenille Kraft Big Bag of Plastic Buttons
PS: I made some extra sets! You can now buy one in my etsy shop!
