Vintage Mustard Fabric, from yummygoods (blog) on Flickr. As Robin confirmed for me in the comments, though, the more accurate term for the 70s yellow is “antique gold.” Mea culpa! I was but a little girl in the 1970s. This fabric may or may not be from the 70s, though, and I would call the yellow more mustardy than antique gold-y. It is good and harvesty, I can say that.
