Gauge does not matter for this pattern. This can be made with any yarn. The thicker the yarn, the bigger the plush!
Use a hook that is at least 1mm smaller than the recommended hook on your yarn, so that the filling does not show.

Materials
One plush yarn (shown here as purple) and appropriately sized hook
One worsted weight yarn (shown here as white) and appropriately sized hook
