So far I have had 2 that I couldn't use anymore :( and these are quite deep and wide.
Some of my ideas are listed below: maybe you can help me suggest too.
-use to boil water/liquid only
-remove the handle, use as plant pot
-donate to op shop
-use as bucket for simple washing in the sink
-wrap with colored plastic/paper and use as fruitbowl, or putting away toys
-turn upside down as a low seat on the floor
-sell as metal scrap
