I drink far too much tea and struggle to reuse all the metallic foil bags that most of my tea is wrapped in. I have used scraps of this material in cards (eg see this card) but that doesn't really use up that much of the stuff. However I recently discovered a great way to reuse the material, by making envelopes for greetings cards. The foil package is just the right size for a fairly small greetings card, I cut off the ends of the packet, glue one end down and leave the other as an envelope flap. Address labels can be glued or taped on the front.

Excellent article on reuse on the new Ooffoo website here.
