Lais Williams - Want your house to look really retro? Try out a design book that was published during the era of the aesthetic you're trying to achieve. I found this 1955 Home Decorator and How-to-Paint Book, published by Sherwin-Williams, on Etsy.
I agree that "Applikay Crystal Green over Super Kem-Tone Caprice Yellow make the living room gay."
I wonder if you can still get an "Applikay." I've done a brief Web search and turned up nothing but
more of these books and ads from the '50s. I really like the one just below with the random cross-
hatching. (They call it "the Birchwork Design.") It also seems like the pattern least likely to look
screwed up if you got the alignment wrong. I bet these things were a nightmare to use, and that's
probably why you can't buy them anymore...
