Measuring diagonally across your card find how long it is in that direction. Then add one inch more and cut out your paper that size.
With the card lying in the center of the cut paper, fold in the sides, bottom and top.
Trim away the four tiny triangles created by the folds. (See the little notches cut out next to each of the big triangles. Those were the little triangles I removed.)
Turn the paper over. For extra durability, run strong adhesive (like tacky tape) as shown in the picture above.
Turn your paper back over. Fold in the sides first and then secure the bottom flap to the sides.
Note: Extra thick paper projects, like the napkin fold, may fit more easily if you add an extra 1/2". That's what I did and liked the results.
To give a finished look, consider using the corner rounder on the top flap before securing the envelope.
I am so excited to have found this envelope recipe. Now everything I make will finally fit in an envelope.
Thanks for stopping by! Sending Smiles, ;-) Joanie
