Have some old paper that's been sitting around? Don't love it anymore but feel you have to use it? Or maybe your stash is just huge and you want to find a way to whittle it down but actually DO something with it....
A quick way to use up your old paper is to make cards with matching envelopes. I started with this paper.
What you want to do is make the envelope FIRST. You can put your pattern on the outside or inside - just keep in mind that to mail it, you may need to use a white label for the address area if you use the pattern outside. These are A2 sized. I made one envelope with an 8 1/2 inch square cut from the paper. There was plenty left for 2 cards and to line the flap of the second envelope. I also like to punch the flap with a border punch.
Then you use whatever scraps are left on the card. If you've got enough don't just use it on the front, use it on the inside, too!
Voila! Some not-so-great paper becomes some pretty good cards with matching envelopes!
