Once upon a pillow, I decided it was time to dress up the bed. I decided on shams and it gave me pause to think. What exactly is a “sham”.  Further, I realized that there are shams, and there are more shames. Like Bubba Gump shrimp, you’ve got European shams, king shams, cushion shams, basic pillow shams…sham, sham, sham shammity sham! In my mind they’re all just pillows, and I had simply merged them into my brain as one lump sum. Well, they’re not, apparently.
