I've been gardening and one of my large plant pots dries out quickly. I decided to get a tray to put under it to hold some water & help the situation. I was going to go to the store to buy one but I took a walk on recycling day. Lo and behold I found the answer to the situation. In someone's curbside recycling there was a large, clear, round, plastic tray which I believe had been the cover over someone's birthday cake. Perfect! I took it home, washed it up and put it under my plant. There's my frugal for today.
