I made these for Trey's Birthday invitations this year. I made up my own template but I found one online by a gal named Jessica Jones that you can print here.
Using the template cut out your paper. I thought it would be cute to add some paper on the inside of the envelope. So I glued a rectangle of paper onto the top of the envelope. It adds a little extra something. You can also do this in ready-made envelopes.
They are so easy and cute. They would be really great with double sided paper as well!
Give them a try!
