Originally I thought about using the covered buttons for a necklace or possibly a few rings, but for some reason I ended up making a headband (which is usually the case with my crafting!).
Fabric of your choice
Button kit (with plain-back buttons)
A basic elastic headband (not pictured)
All you do is cover the buttons (which is explained on the back of the button kit and is extremely simple and fast), hot glue them to the headband, and ta-da! You are finished.
