First, I had to fold the curtain in half. Then, I used the rod iron seat bottom to the chair and the oblong seat bottom to the love seat to measure and cut the two sides of the cushions.
I had to cut two sets for the two chairs. Please remember to make your markings 3/4″ to 1″ away from the edge. Maybe even more. The more fluffy you desire the cushions, the more fabric you must allow from the edge.
