Dwayne -
We have the same shades and I've wondered the same thing about day shades. Just have not looked into it, yet.
The valances are held up by 2 brackets on both ends, between the shades and the wall. We had to replace our shade over the table a few months back. DO NOT over-torque when you put the screws back in. You'll end up having to put in different sized screws... Hope this helps - Bill.
