Whenever you are painting, the natural thing to do is wipe your paint brush against the edge of the container. This results in a messy, sticky outside of your paint can and paint waste. Why would anyone want to do this when this problem can be solved with an ordinary household item (that costs barely a cent) in just a few seconds.
Step 1: (and Only Step!)
Place an elastic band around an open paint tin (as shown in image). Paint as per usual but instead of wiping the paint brush against the edge of the tin, wipe you brush against the elastic band. All the excess will go back into the tin without messing everywhere.
Simple as that! Hope you find it useful. Please comment what you think at the bottom!
