What are you most proud of? That I was able to sew the side piece of the cushion on without much of a hassle getting it to fit. What advice would you give someone starting this project? Sew the seams exactly 1/4" so the circle will lie flat. Use LARGE buttons to cover the center of the circle. Have a VERY long crafting needle because the pillow is really thick. Ask me how I know. Use very strong thread when sewing the buttons on since you have to tug at the center to make the indentation.
