NEW Go Anywhere Portable Blackout Blind has all sorts of uses - professional, home, travel or holiday - wherever temporary blackout is required, but also, because it attaches to the glass with suction cups, and the fabric can be cut without fraying, you can use it to blackout irregularly shaped windows.  Simply cut the fabric to the shape and size you need (ensuring for best blackout that the fabric is a little larger than the frame) and press it against the suction cups on the window.  Works for triangular, circular, arched or non-standard size windows.

Available in black, cream and white, and in 3 sizes:
