Another of my amateur fumbles is the gear shift knob in my car. The OE one was leather, and on an 18-year-old car was beginning to show it’s age.
The knob is made from spalted beech, as is the cigar lighter blank. Both are from the same board, and are ethically sourced. I have not been turning much recently due to a whole host of issues. I’m currently looking through my bits & bobs, hoping to build some enthusiasm.

There’s also a button over the 12V socket in the boot. The original cover was knocked off by the dog. This is made from yew.

Who knows, maybe someone else will fancy making one for their own vehicle.
