Collections Etc Elegant Insulated Scroll Pattern Window Curtain Panel with Rod Pocket Top, Sage, 50" X 63"

I have purchased this Scroll Insulated Curtain a few times in different colors. They are so pretty hanging in the areas I put them in, and they look very expensive when the room is bright, whether it's daylight, or room lighting. However I am disappointed that I'm not able to get the 2nd valance for the 2nd window curtains in a different room where I moved the bedroom furniture. I'm a seamstress and trying to figure out if I cut the first valance I have from the single bedroom area, in half lengthwise in order to make a valance for the second bedroom window, and hope the shorter length will still look nice at both windows. Fingers crossed that my plan works well!
