Handkerchief

I swear I had a handkerchief that I used to blow my nose maybe 37 times today. I've just waken up from a 3-hour siesta and I can't find it. I mean, I blow my nose before lying on the coach for 10 minutes -3 hours ago, and now I can't find it.

Should I use toilet paper, or wait until I find it to blow my nose?
