Removed shades and had short curtains made of ultrasuede (which is totally light blocking). Now they can be pulled over all the window or a portion can be left open for breezes. We left top wooden valance but removed side valance so they stack nicely when opened without covering any portion of window. No holes for light to seep thru and the very best part is they can be easily removed to be washed in machine (which they do very nicely)so we are not traveling the next year with the dust that got embedded from Arizona snowbirding. I never could figure out how to get the shades totally clean. One extra bonus is that the material curtain also functions to give a sound deafening effect to the inside and adds a layer of coziness. It has been a win-win all the way around.
