Help! yarn for allergic cousin?

[nuknitter]

I can find plenty of subs for a chunky/bulky weight non-animal fiber yarn, but problem is, there's not a lot of straightforward reviews about them . I'd love y'all's opinions on what I could use for my cousin's Xmas gift scarf:

-chunky/bulky, smooth so has good stitch definition with cables, preferably in a red color, SOFT - meaning a silky "hand", not a yucky plasticky feeling when you run your hand over it (y'all know what I'm talkin' about).

This would be a cinch if she wasn't so dang allergic. I know KH'ers got the answer!

I'm planning on doing Butterfly Morning's Chunky Braided Scarf for her:

and am planning on getting a lot of it done while traveling the next 3 weeks...
