Ok. Here are the pics of one I finally finished. Will be using command Velcro strips on the inside of the skylight to install so will be removable.
Initial piece of the chrome bubble wrap cut to fit the inside lip dimensions.
Then sewed a layer of microwaveable material on the side that will be facing inside the coach. This is made for putting potatoes in and cooking in the microwave so should be good lite weight insulation material.
Next a layer of better looking material. Waiting for the wife to pick some decorative material if she want to dress it up and I’ll make another using that.
Then on the side that will face the skylight Velcro all the way around.
Will be doing the same thing for the skylight above our bathroom sink.
Will be going out to storage this week so will post the installed pic then but I think you get the idea.
Maybe $10 total in materials not counting the sewing machine I bought and the time to learn how to use it.
Will just cover the clear part and the lip around that where it is all the same height.
