I am looking to make my mother a design wall for christmas out of a roller shade but all I am finding are very expensive shades online. My questions are does it matter what the shade is made out of for the flannel to stick to it better? What type of glue? Where do I buy a shade that wont break my bank and finally will she love it or will it be a nusance that never really rolls up right? thanks for any and all tips :-)
