Like the feel of a heavy stainless steel shift knob but hate getting burned in the summer and the chilly feel during winter? Try wrapping it in Alcantara or some other material of your choice:
It feels fantastic to use, much better than polymer or plain metal knobs.
I printed the template here to scale for my Blox knob that I got off NASIOC:
The circumference of your knob = length of fabric template + width of template, use that formula to print to size.
I'll grab a daylight pic for you guys tomorrow.
