Could you be more specific about what you wuld like? Do you mean shades, curtains, blinds, something to apply to your window glass...?
Are you wanting coverings on the windows mounted outside or inside?
What is your goal in having the windows covered - block sunlight, need for privacy after dark, etc. ?
Rose....Towels make cute curtains...you can sew or use fabric glue.
