Remember this easy DIY I posted a couple of years ago? This is along the same lines. Big Girl gave me these little glass votives that she took the candles out of by putting them in the freezer for a day first. She popped the frozen wax out with a butter knife. They have been hanging out in my sewing room with pins in them. The problem is if they tipped over, pins were everywhere.
Foot + Pin = Ouch!
