Step 1: Gather Supplies
2 caps from 1 liter pop bottles
1 2 liter pop bottle, clear
copper spray paint
1 spade style drill bit
Step 2: Make Lens
Drill a hole for your eyepiece. Repeat for other cap.
Place your cap on the shoulder on the 2 liter bottle.
Mark its outline twice. Cut out your lens.
Trim to fit inside of the caps.
Step 3: Make Lens Holder
Yours will be different, I have a fat head :)
Fold paper in half, measure in 1/2 of the distance between eyes, and place a cap that far in. Trace around it. Add a margin, and draw the shape for your goggles.
Cut hole for lens smaller the outside of caps.
Trace on leather, and cutout.
Step 4: Finishing Touches.
Put the lens back in after the paint has dried.
Put the caps into the leather.
Glue the caps into the leather.
Add little screws and such for detail. This is really up to you and your taste. I drilled hole in the caps to help hold the screws.
Add straps, and your finished.
