The Button Jar. As a child, I entertained myself with the contents of my mother's button jar. On a rainy day, or during a sewing project, she would take out the buttons for me to play with. When people discarded clothes, they often removed the buttons, to be saved and used again. These buttons would end up in a jar, tin or someone's sewing basket. I have a button jar for stray buttons and I've learned that many other people also keep a container of odd buttons. I often use buttons when scrapbooking!
