Re: “Knit Scarves, Not Art” [“Postmarks
,” May 7]: I'm guessing your grandmother didn't crochet anything nice for you as a child. By your own admission you state, “Each time I give a sly smile and answered, 'Oh, it's art.'” If you have to explain that it was art in the first place, doesn't that mean the art misses delivering a point? That's like having to explain a joke. Wasn't the Texas Department of Transportation recreational signage serving a different purpose? We assumed the blue signs were for high-water markings under the train trestle. Yarn bombing is not utilitarian if surplus TXDoT signage and water barriers qualify as acceptable displays of art. Yarn bombing is the Banksy way of saying, “You may not have noticed this before, so I think I would like to warm this up." I, for one, smile every time I see Magda Sayeg's yarn bomb. I also smile every time I snuggle up in the crocheted cover my Nana made for me when I was young.
