The folks over at Wish have devised a cute and clever way to repurpose those bags of spare buttons sitting in your junk drawer. Use them to keep pairs of earrings together by slipping their posts or hooks through the button holes. If you sport pins or brooches, this will trick will work for them as well. I must say it's a pretty useful idea; my post earrings are always getting lost. Of course, I've got my hook earrings neatly hung on the shutter earring display I made. There's a reason why the expression "cute as a button," is what it is: buttons are darn cute, especially a collection as colorful as this one. So, to learn one more way to repurpose your remnant buttons, read more.

You can use a big ole collection of buttons to cover the back of a medallion chair. Though the project is simple but time consuming, it's worth it, as it can add personality to an otherwise prim and proper piece of furniture.
