To make a money jar, we need a jam bar, a cover, painbrush, cutter, cloth and some acrylic paint.
First, wash the jam bar throughly. Then, wipe it with a piece of cloth. After that, use a sharp cutter to make a rectangular hole on the cover. We need a brush to paint some colourful pictures to make it attractive.
