Using up scraps of folded bias binding, I sew it along the right side of the layered muslin and cover fabric, leaving a space so that I can thread through my cording.
Tighten and tie the cording and ta-da! a new ironing board cover! I like it a lot more than that ugly green thing!
I tested it this afternoon on some 3" pineapple blocks.
4 down- 21 to go. Better get back to my sewing machine!
