Sometimes you have to find and save something for awhile before their purpose is revealed.
Like the base used on my Christmas in a pickle jar. (the inspiration for this project)
This past summer we had a new ceiling fan installed in my son's room. It was flush mounted to the ceiling, so, they didn't use all of the parts that came with the kit. I came across the unused parts in the garbage and decided to save them.
FYI...It's not hoarding if you use them. (I'm just saying.)
Because I wanted to be informative when writing this post, I emailed my brother for the correct name of the part. I am told it is called a canopy. I glued the canopy onto the jar using Beacon Glass, Metal & More Premium Permanent Glue.
