I've always envisioned making a clock out of paintbrushes, and I finally figured out how to bring my idea to life.
The size can be anything you want, as long as you follow a compass. Our clock ended up being 2' in diameter.
I found a large clock at a thrift shop. I was mainly interested in the battery-operated mechanism and large hands.
I needed something on which to mount the hands with enough depth for the battery mechanism. A tuna can to the rescue! I sprayed it metallic blue, drilled a hold in the surface, and mounted the mechanism and the hands. I took pictures when I removed the parts so I could follow how to reassemble them when I was ready. The inside of the can provided the perfect void for the mechanism/ battery pack so I could just hang the tuna can on a screw and remove it easily for battery changing.
I chose primary and secondary color paints, saturated each brush tip, and laid them flat on plastic wrap to dry.
We used the soon-to-be-discarded clock background to set where our brushes would hang on the wall. Having pre-drilled a pilot hole in each brush, we hammered small nails to mount the brushes into place.
The clock hangs in our art studio space which is just off the foyer and is very visible to people who come over. It is often a conversation piece. It brings me so much joy every time I see it.
