I used 5 skeins of Bernat Softee Marl and half a skein of solid.

This pattern is adjustable. It can be made much larger. Instructions are provided.

If you do not have a 3mm hook, a 2.75mm hook will do. This hook is only used for a cinched ribbing. You can continue with a 4mm G hook for a loose ribbing.

This pattern relies heavily on charts and post stitches. It may be very challenging.
