Here's a stand-up tri-fold card I made for the first time and that was quite an afterthought (the stand-up part). The lower part originally was much longer I thought it took away from the top foldover flap so I made it shorter by making it a stand-up. I actually like it that way! In order to mail it I will crease it in the middle at the bottom so it will fold flat.
Thank you Kelly (KVRLVN) for the lovely die cut. The green paper was a little bright for what I wanted so I sprayed it with Perfect Pearls in Heirloom Gold to mute it down a bit.
I also made use of my Spellbinders border brackets. I found if I put a little piece of scotch tape on the die to hold it to the paper it works a lot better. I used two of the dies, one to cut the edge and the other for the die cut pattern.
