Cut your cans in petal shapes. I try and make different shaped petals for contrast. Spread the petals and pull down; then drill a hole in center of each can. Make sure you sand the edges of each petal – it’s not as hard as you think. I used a nail emery board for the first one. Spray paint – I used an enamel white and I did one in yellow. Let them dry completely. Find a draw pull that would work for a center
This was a draw pull I got from Hobby Lobby for .50 a few years ago. Slip petal onto screw back of pull I then hammered an aluminum pole flat on the end and drilled a hole in it to secure the draw pull and added the bolt.
