Best Flexible Black-Out Curtain

[Josiahdr]

Anyone know of the absolute best black out curtain material, insulating properties a +.

The plan is to run a guide wire from the front to rear on either side, top and bottom. Put eyelets in the fabric, along with a few magnets, and have pieces two windows in length.

This should allow us to completely block all side windows and still allowing us to condense them. So when boondocking we can keep our open concept and 360 views.

Any thoughts?
