Re: Stuffing envelopes - I think you will find these days that companies either have a folding and stuffing machine (my old work did) or they out source the printing in the first place to somewhere that can fold and stuff as well. When I did work places that did need envelope stuffers the staff usually called people they knew (friends & relatives) so put the word out to people and they might think of you when something comes up.

Good luck to those that are looking - I am beginning to think there needs to be a sticky thread on work from home ideas.
