You can make this pillow as a 16" x 16" or 18" x 18" size. If you like your pillows on the firm side we recommend getting a18" x 18" or the 20" x 20".
We have included a zipper in our kits for your pillow.
If you are purchasing a kit for this project and need the pattern, you will need to say "YES" to the option of pattern then it shows up in the drop downs. Kits DO NOT come with the pattern. Thank you
