I'd really like to cover my walls with fabric but I don't really know how to best go about attaching it. I'd really prefer not to hang it or have it loose and curtainy, but I don't know if any other way would work. Would staples or tacks do the job? I'm planning on using toile and I'm not sure if it'll be too heavy for tacks to hold up. I don't want the staples to be too noticeable if I have to use them, either, and I'm wary of the starch method because I'm not sure how that will affect the walls (I'm moving into an apartment and can't have wallpaper.)
Also, I'm terrible at math and I don't know how many yards I'll need based on my room dimensions. Surely there's some sort of formula to figure this out other than just measuring?
