Find your local plastics distributors and ask for lexan thermoclear, Thermoclear, Verolite, Twinwall or polygal structured polycarbonate sheets. They are typical thermoglazing glazing sheets for lightweight, high impact resistant & formable sheets. They are usually 48"x 96" and could be ordered up to 72"x 144" so you could under-cover in one sheet! They are clear, opal white or solar bronze. No problem with clean steel/carbide-tipped blades. Go slow and it doesn't melt. Minimal tools? Easiest, score & snap break. If anyone is able-$ and technically inclined, precise laser/water cutting is best.
