This is one of those “keep yourself busy or else you’ll lose your mind from the emptiness of your life” projects. Slipcover your potholders by Doris:
“Cut fabric twice as long as potholder, plus 3″ for tuck-in flap and 1.2″ all around for seams; taper sides of flap. Bind edges, making a 2” loop at one square corner. Fold crosswise to make potholder pocket, leaving flap free. Stitch sides. Tuck flap over the potholder.
