What does everyone use for labelling their rugs?

I am looking at Tyvak which comes in various versions - I would assume flexible or soft would be the most suitable for our application.
Also how do you attach the labels to the rugs - glue, staple or sew?
If glueing - what sort of glue?

we use tyvek tags and tagging gun for fabric or clothing just get one with a long needle to get thru the thick
rugs, you can get them at fabric store or even some office supply stores.

we used paper tags and safety pins to attach them to the rugs.
