I made this star as a gift for my brother Michael. I save my bottle caps grouped by kind in separate containers. This allows me to design with them easily. Bottle caps are circles; thus they tile on a hex grid. I make a paper drawing first, using a 30-60-90 triangle to create the hexagonal forms.
I have made bottle-cap medallions that I applied to the kitchen cabinets of our cabin. Click here to take a peek at them.
