You can add a framesheet. HDPE is a good material; 1/8" should be a good thickness. https://www.amazon.com/Polyethylene-Off-White-Tolerance-D4976-245-Thickness/dp/B000ILG0TQ/ref=sr_1_4?crid=14EQH60HNXPMY&keywords=hdpe+sheet+1%2F8&qid=1564506841&s=gateway&sprefix=hdpe+sheet%2Caps%2C150&sr=8-4

HDPE is very easily cut with normal woodworking tools, and you can sand a nice smooth edge with normal sandpaper. EDIT: And for a 1/8" thick sheet, you could cut through it by making repeated cuts with a utility knife; go slow and don't cut yourself!
