Be forewarned:
NEVER DYE WALIS TAMBO BRISTLES IN JOBOS DYE. IT STINKS TO HIGH HEAVEN!!!I was supposed to use it as a substitute to Woodland Scenics' Field Grass because I was running out of tall grass for my diorama entry for Motorex last year. But scrapped that idea when my experiment to color it went wrong, hence the above warning.
I agree it's good for depicting certain types of field grass, particularly in my mind wheat, and maybe even corn fields.
Another way is by using the 'twine' or 'thread' of those hemp ropes, as suggested by one of the judges at Motorex. Same judge also suggested using shredded plastic.
