I just used Paint and hand drew a wing rib. If you wanted to get real fancy you could use a CAD program or find a NACA airfoil you like and use it.
Step 2: Print and trace
Print the airfoil out in banner-size, cut it out with an x-acto knife, and trace it onto your wood.
Step 3: Cut it out
Use a jigsaw and cut it out. Then sand it up really well, cleaning up any jagged edges.
Step 4: Drill the peg holes
Drill the holes for the pegs, i marked the depth i wanted the holes with a sharpie on the bit and then drilled to that point.
Step 5: Time to stain
Hang the shelf from the ceiling with some newspaper underneath and apply your stain. I only used one coat of stain, because I liked the color after the first coat. Add the pegs (previously stained) with some wood glue while the stain is still wet on the shelf to aid in adhesion. Then apply polyurethane, I used three coats lightly sanding between each. Finally, apply some paste wax to give it a good hard finish.
Step 6: Hang on wall
I attached two picture hanging brackets, used a level and hung up the shelf on my wall. I made it specifically to hold my four headsets. I hope everyone enjoys!
