An easy pattern worked in the round for a driver head cover.
This is designed to fit the larger, wedge shaped drivers with increases worked on one side to better fit this shape.
It is customizable in that the sleeve can be made as long as desired, the actual head cover can be made larger ( or a bit smaller) depending on the yarn chosen and gauge and the actual size of the driver.
It has been knitted in both yarns suggested, needing only 1 skein.
Easy to measure as you go for a perfect fit.
You can opt to add stripes- maybe for your fav school/team, finish with a pompon or tassel or knit Icord and add a number tag.
