I didn’t like making these cards in the past because it always seemed like a struggle to decorate the front. Then, as I was creating my sample to familiarize myself with the fold I had an ah-ha moment. If I cut a 5 1/2 ” square of the pattern paper, cut it in half, and then trim the corner just like I did with the card, I would have the pieces I needed to decorate the angled parts of this card!
Here is a process video showing you how to create this card (Which I do consider a fun fold now)
Diagonal Trifold Card
Start with a piece of cardstock 9 ¾” x 5 ½”
Score at 5 ½”
Fold the corner of the 5 ½ x 5 ½ section in half diagonally.
With the corner folded down, trim the card to 4 ¼’ width (you should only be removing a small corner of the folded square and matching the width with the “back” of the card base)
Cut a 5 ¼” x 4” (or smaller if you want) for the “Inside” If you cut a 5 1/2 ” square and cut it in half, you will have the correct angles for decorating your card frong.
