Now that I fully embraced (today) this 100th 'calling' as paper designer (we can go through the other 99 another day...) I have been actively researching all my options in paper creativity. I am thoroughly into envelope making because A) it sounded like something I'd like to do and B) I don't have any more friends (we can discuss that subject another day as well). So for now, I can share with you some of my finds in this fine art.
Let me start with this, a recipe for envelope glue. Why you ask did I start with that? Well dear, if you are anything like moi you have an attention span of a gnat and will jump right into the envelope making and then will stumped on how to seal it in order to actually put the darn thing in the mail. A tiny sticker just won't do, unless of course you want all the contents falling out and someone knowing that your nickname is stinky bottom or something (only thing I could think of).
You are going to need to make some templates or buy them (lucky for you to have moola to purchase these necessities) I had to make my own. Lucky for you I found this incredible resource and she also happens to be completely organized and seemingly has a much, much longer attention span. Envelope resource mother lode here..
