One item that’s an everyday necessity that people rarely buy is the humble pillowcase. It gets used and abused on a daily basis, becoming threadbare and faded, but rarely ever replaced. A walk through the linens aisle at any store shows that for simply being folded and sewn pieces of cotton, pillowcases and other linens are certainly not cheap. Fortunately, with a few of the most basic sewing skills, $5 or less and an hour, you can make comfy, custom pillowcases you won’t be embarrassed to drag over to a sleepover.
