I love a drop cloth curtain. Maybe a little too much because I have them all over in VT. If this is a little boring for you just add some contrasting ribbon (just use fabric glue - no need to get all fancy). I bet this would be an awesome project for Makenna.
Curtain Tiebacks by Shakespeare Design. The stunning natural beauty of tan leather coupled with a brass horse bit adds texture and a stunning feature to sheer white linen curtains. Enquiries to www.shakespeare-design.com.au
This is my Pinterest inspiration. I really liked the drippiness and the weave - an interesting detail I had never seen done before. My version is fuller so that they can actually function to close if needed. The window in the dormer alcove is scaled down: shorter and more narrow.
