Hat as..

Looking at threads in this forum, an idea has just flashed past my mind and thought it should not go waste. Has somebody tried to grow plants in old hats? I have seen and been using old pairs of shoes for that purpose with some interesting success. But I don't think anyone using hats suitable as containers. I don't have even one (we don't use them as a custom) to experiment. Just thought of of sharing the idea. How about caps?

I have done so in a cap, but not a hat.
I have taken an old straw hat and sat a potted plant in it but actually planting a plant in the hat itself, then no; just a cap.
Have grown plants in an old pair of jeans tho; well shorts once I cut the legs off. Has been along time ago since I've done that tho. Wish I had a picture to show, but didn't take one; was a long time ago; no one to share the photo with at the time.

I think an old gardening hat would be fun and cute!
