Do it Yourself Quilted Window Insulation Kit - advanced 7 layer material uses suction cups

I haven't made them yet- but think the thickness of the material will really make a difference in heat in RV. I thinking of using velcro to fasten to window ( like the EZ pass )instead of suction cups. Should be done in June.

We had these window coverings in our RV so we knew we wanted them in our recently purchased boat. We made the measurements, but didn't have the project space to cut the material nor the expertise to sew on the edging. A local canvas shop did a great job with that, and we're very happy with the result.
