wow Im going to have to check that out thanks for sharing and posting .
Don't get too excited. I just cut and taped the bag my food came in to make the envelope. One more way to recycle!
Good idea - I save kid's meal bags from our visits to fast food restaurants, to use as lunch bags on field trip days (when the teachers don't want to hassle with keeping track of lunch boxes) but maybe I'll make a few envelopes instead. :^)
