Paint four yardsticks red. Paint three yardsticks red from the 16 inch mark on. Paint three yardsticks white. Paint three yardsticks white from the 16 inch mark on. Allow to dry, recoating as needed.
Tape off the half painted yardsticks at the 16 inch mark and paint the remaining section blue. Allow to dry completely.
Paint the stars white.
Position yardsticks so they make a flag shape, ensuring that the blue section is at the top left.
Flip all the yardsticks over. The blue section should now be at the top right.
Cut the two extra yardsticks in half, at 18 inches, to make four support sticks. Twist wire around one of the support sticks to create a hanger. Glue the support across the back of the flag, a few inches down from the top.
Glue the other three support sticks across the back of the flag as well. Weigh them all down with cans or something else heave and leave to cure for at least six hours.
Once the glue has fully cured, flip the flag back over and glue on the stars. If you are using small stars, it's easiest to use a small paintbrush to paint wood glue on the back of each star.
Display by hanging the flag on a wreath hanger that can hold at least five pounds.
