I was able after Christmas last year to purchase lots of Christmas plaid dish towels for cheap. These are directions for making a small pillow case (for a travel size pillow) but could easily be made as pillow sham for regular size pillows. ( Holiday Bed Spread out of these same towels https://www.instructables.com/id/HOW-TO-MAKE-A-HOLIDAY-BEDSPREAD/ )
Dish Towels (2 per travel pillow - approximate 6 for a regular pillow) amounts could vary depending on the size of the towels and pillows
Yarn to match or compliment towels
Step 1: Sewing Towels
I used a simple blanket stitch, (see several pictures) In one side out the other and over yarn to make a loop stitch.
See picture for instruction on making a pillow sham.
