Steps:

1. Remove any loose, splintered, or jagged wood by hand.

2. Grab three straight sections of cardboard.
3. Apply Vaseline to one side of each section of cardboard by hand. Vaseline will prevent the wood filler from sticking to the cardboard.

4. Hold one section of cardboard underneath the corner needing repair with the Vaseline side facing up.

5. Apply wood filler to the corner by squeezing the tube.

6. Position the other two sections of cardboard on either side of the corner to help shape the filler into a right angle. Place the sides with the Vaseline on them toward the filler.
7. Use a putty knife or plastic butter knife to smooth filler if needed.

8. Remove the cardboard sections before the filler dries completely.
9. Allow the filler to dry for approximately six hours. The filler may take less time to dry if repairing a smaller section of the apron. For dime sized reparations, the filler will take approximately two hours to dry.

10. Sand the filler with 120 grit sandpaper until it is satisfactory.
11. Repeat steps 4-7 if the corner is not the desired shape.

12. Paint the finished corner with the desired shade of paint.
13. Allow the paint 3 hours to completely dry.
