To begin, I corrected the odd shape that the sack was sewn in.

I turned the sack inside out, ripped out the original seam in the bottom of the sack, and replaced it with a straight seam.

For the ties, I cut four strips of linen that each measured 1.5″ by 30″. I wanted the bows to be long for this project.

To finish them, I folded them in half and sewed all the way down the long edge. I tucked one end under to hide the raw edge inside.

Using a large safety pin on one end, I turned them right side out. I pressed the seam flat and topstitched all the way around.

I sewed the four linen ties to the inside of the pillow. Since the pillow cover was about 14 inches wide, I placed the ties about four inches from each edge.

I slipped in my DIY drop cloth pillow insert, and voila! A super simple pillow cover, for less than five bucks, and not much time.
