I actually came up with a good idea last night. Found free high resolution images of rock textures from google. Then priced having it printed online, it was only $29.99 for 24" x 48". I can then laminate it and attach it to the same way that the backgrounds from the lfs
are attached. I guess you could even do the sides if you wanted. Great ideas though, maybe this should go into the DIY section. This is the backing i am leaning towards.
