On a whim I went into a thrift store on the way home looking for nothing in particular. I eventually found the craft section. I picked up black and white yarn for a mime hat I'm going to weave. I dug around and also found 2 bags full of buttons for $2.50 each. So many crafts need buttons. Everything from doll and teddy bear eyes to hanging signs to crazy quilts. Some projects take quite a lot of buttons, like those dolls with the button arms and legs.
I also got some wide tooth combs and Afro picks. No, I'm not planning on growing an Afro anytime soon, but they will be great to tamp down yarn in my weaving projects.
Anything you get from a thrift store extends its life and keeps it out of the landfill just a little bit longer.
