There is wrapping paper still being used that is at least 8 years old and definitely showing it's age
Even after they explained to me that they don't rip or throw away the paper, I still tore into some gifts, especially if it was obvious that the paper had already been used. It's 1/2 the fun!!!! I can't imagine anyone tossing a gift bag in the trash after one use if it "appears" new. (Bet some people here do.)

Yup. That would be me. I don't have any desire to pile more stuff in my basement than necessary, so wrap/bags/tissue goes in the recycle bin once gifts are opened. Plus, I usually go with a "theme" every year for my wrapping, so what I buy one year won't go with whatever I end up doing the next.

We do not reuse wrapping paper, that is ripped up and thrown out or burned. Usually tossed because we don't like the way coated burns.
Ribbons are tossed. Tissue paper is usually thrown out, unless it's in particularly good shape, but even then it is only reused on family. Gift bags are reused regularly in our house, I rarely buy new gift bags for anything. We have Christmas bags we've been using over and over for at least 3-4 years now. In that vein I'm starting a project, I'm buying up fabric scraps and making gift bags out of them, those are absolutely reused!
