Peacock is a dark turquoise that is more green than blue.
#4 Invisible zipper yardage is so easy to use. I split the tape & sew on the bottom of all the pillow backs (or fronts) leaving 2-3" between pillows. In quilting this is called chaining. Then I do the same to all the fronts. Cut off leaving a few inches tape on each pillow & apply the pulls or heads. Sew up the other 3 sides of you pillow & you are done!
