Disposable kleenex are definitely what I prefer for when I actually have a cold where my immune system is sending buckets down out of my nose.

But for the once-every-couple-hours-my-nose-itches-and-I-need-to-do-something, well, a handkerchief works well.

Huh. And I don't actually use my handkerchief for my glasses, that's what my shirt is for. =)
