Black Rubber Bands?

[|||| Philip ||||]

Hi all,

I'm patching out a MWI and adding a few cosmetic goodies such as blue LEDs,
etc. I would also like to put rubber trim around the big red knob similar to
the knob on the Alesis D4 drum machine or like on most camera lens. Has
anyone seen a supplier of black rubber bands or small drive belts on the
net?

Thanks
Philip
