There are some really cute things there! My mother was a quilter, and sewed all my life, when she retired, quilting was her greatest passion. I have big Mason jars full of buttons that she kept. Anything that got thrown away got the buttons taken off first. I think I'll have to make one of those chickens from her buttons.
