Step 3: Cut the holes for the cord and finish taping it up.
Tape the fabric hem with the cording ( or old drawstring whatever works) laying inside it. When you get to the end decide what is the back or bottom of the chair cover, where you want to tie the drawstring. Cut two holes there about an inch or two apart, on the folded area of the fabric. Thread the cord ends through the holes and finish taping the edges.
