This pattern is intended to be made round by round until you reach the desired cushion size. Once you’ve made the front and back pieces, you’ll attach them together and then move on to create the scalloped decorative edging. This pattern is designed so that you can end it after any round to create your desired cushion dimensions.

You can also use any yarn (it is recommended to use any combination of yarn held together that makes AT LEAST a worsted weight or thicker) and a hook 1.5mm or so smaller than the recommended hook size.

Since the size is entirely customizable, it is impossible for me to provide you with a correct gauge or yardage calculation.
