Let’s get to it.
2x 24”x10” Reflectix (Home Depot)
3yds Duck Canvas Fabric
5x 3yd Double Bias Tape (trim)
All purpose thread.
Sowing Machine - unless you’re that good by hand
Take the widest/tallest measurements for each desired window and use that as your cutout size. Just smash the reflective material into the window and sharpie the outline and mark it so you know which piece goes where.
The crosshatch sowing can be done any way, but the way I did it allows to accordion it down to pack away (like your typical windshield sunscreen)
All in I’d say $50 and 4-5 hours of time.
