I planned on spray painting after the pine cones were attached to the cans, but if you would rather go for a natural look, then paint your can first. I painted one of the cans with a copper spray paint before gluing on the pine cone tips so I could show you what that would look like.
Let the glue dry 48 hours.
Mr. Hobby liked the ‘natural’ look best. I liked it too, but it was not my original plan. I wanted colorful textured planters, so I spray painted each of the cans with a gloss spray paint. It took 4 coats for good coverage. Allow each coat to dry fully before applying the next.
After the paint dried, I filled each can with sand to about an inch from the top. Next, I added little white rocks that I found at the dollar store.
