Ouch! Sure, I remember that foil also. We didn't have the foil, thankfully, but I'd seen it in other houses. We did try grasscloth twice in the living room! I don't think that was so common though. It replaced a really loud somewhat floral patterned dark blue on white. The first grasscloth we had was a brown with a blue background; the first night it was up, the wall was crackling all evening long as the paste dried! Well...that experiment turned out to look a little too "grass hut" for mom's taste, so that got taken down and an all-blue grasscloth was put up in its place. When that started to get faded and a little dusty, that came down and the wall was painted, and remained that way until the house was sold. Consider this in a slightly greyish hue of blue and you've got the grasscloth nailed: Yes...I know.
