What are the ways to cut a roll of fabric? (diolen)
I want to pre cut it to strips so save time

Is there a cheap way to do so?
Also, do Easy composites offer this kind of service?

It cuts like Kevlar albeit not quite as difficult. 

You don't see that many twill format narrow tapes as a plain weave is much easier to manufacture.  Many of the twill formats are woven as a braid, be it flat or tubular.
