To make protection on the brush, you will need an iron cover from a can with a diameter of ten centimeters - smaller caps will be useless, but with a large diameter they are uncomfortable:
From the tool we need a knife with a strong and powerful blade for cutting a hole in the lid:
Let's start making it ourselves: in order for the lid to fit snugly on the hands, take measurements from the pen and apply dimensions to the lid using a felt-tip pen or a sharp object such as a nail (no pencil will be drawn on the smooth surface of the lid). Then we lay the lid on a flat wooden surface - a piece of board will fit, and with a knife, carefully, cut a hole of the right size. We dress the lid with a slotted hole on the handle of the brush so that you can then freely hold the brush by hand. To prevent paint from leaking through the edges of the cut hole, you need to coat them with silicone sealant. Device ready for convenient painting of the ceiling.
