The grommets we sell are the best in the west! The depth of them allows for the fusible batting as well as the Tote fabric to fit when they are snapped together. NO tools needed, just use the smallest of the two grommet circles for your template (use a pen or pencil to mark the fabric) and cut around the circle. Push the fabric around the front grommet (small circle) and then just SNAP the back grommet on the other side (this one will be on the inside of the Tote). No Problem, right?
