My 12 yo dgs came to my house a month ago and asked if he could make a pillowcase. I said, "Sure, go and check the cupboard in my sewing room and choose some fabric." He came back and responded, "Grandma, you don't have any dude fabric."
So, I bought some "dude" fabric and, when he came this weekend, he made this pillow case. He approved of the "dude" fabric.
