This question is one I will answer with a yes as we have done wall tapestries, college cafeteria drapes, sheers in ballrooms, and on. Now in saying that we always need to come and see the drapes as we need to see:
#1 how they are hung
#2 how strong the material is
#3 any rips soiling etc
#4 if the hem is falling out
#5 any color loss from sun exposure
-and lastly what the material is made of.
What everyone needs to understand is drapery materials are some of the most intricate unique materials out there. They need to be handled by a professional as they can shrink, bleed, or be hung back up wrong. Many times when we get up and see how they were hung we actually notice flaws. We will pint them out, and correct them if possible. This will hopefully make them hang the way they are supposed to, and open and close smoothly.
