Sorry for the inconvenience....I found a typo...and I wanted to add an additional instruction.
1. After you stitch the backing fabric to your linen and before you turn the piece inside out, trim the seam about a 1/4 inch and clip the corners on a diagonal so that the corners will be square.
2. THIS IS THE BIG CORRECTION. Turn down the corners 2 inches. In the instructions, it states to turn the corners down an inch. That's too small. It should be 2 inches. Otherwise the corners will look really wonky and your bourse won't look right closed.
