Is your belt tied correctly?
The ends of your belt should come out of the knot side-to-side, not one end straight up or down. If they don't go side-to-side untie the last knot and make sure the UPPER end goes over the LOWER end and pulls through.
Are the ends of your belt even? If they aren't, undo the last knot and adjust so the tips of both ends are together when pulled out straight form your body. Then tie the second knot as above.
Are both layers of the belt tied neatly together? If not, undo the last knot and slide the outer end under both layers of the belt and then tie the second knot as above.
Congratulations! Your belt should now be tied properly!
