Ocean Wave Shade

This shade is the embodiment of island serenity.
The face fabric is bamboo, a cellulose-based fabric made similarly to rayon with the same lazy, drapey fluidity.  To protect the fabric from the damp salt air, the shade is lined with nylon shower curtain lining.
Four-inch interrupted back tucks stitched horizontally across the width of the shade create the "waves."  The rings and lift lines are positioned at the tucks.  
You can't see from this picture, but the ceiling is angled.   A dustboard holds the lift lines as usual, mounted where the wall meets the angled ceiling, and in order to allow the fabric to come up to the ceiling, a board is secured at right angles to the dustboard, the top edge first being trimmed at an angle to follow the angle of the ceiling.  I think there is a word for this but I can't think of it now, on Friday afternoon!
