I've seen people use liquid starch but I don't know the process. Perhaps that will be enough to help you find your answer if you don't get it here.
The stiffer the fabric the more likely the project will be successful.
Fabric with a backing is more suitable than with no backing.
If the fabric content of the material you are using contains any polyester, it will not absorb liquid starch evenly.
I haven't tried this myself but I've heard liquid starch works to adhere fabric to the wall and also makes it easily removable.
