Yes, being able to craft ropes is a good idea.
Tier 1. Plain rope. ( 4x fibers )
Tier 2. Purple rope ( 4x fibers 2x fruit ) & Hubologists rope. ( 4x fibers 2x xander root )
I like the idea Subcor,

exspecially the materials you mentioned they should requiere,
maybe even having a dye tub, should be the requirement to craft them,
it would seem abit odd pouring colouring over the work bench.
