Origami is an interesting and relatively cheap art form. Heather Shida, who's been making origami since the age of ten and now instructs others online in this art, based this gift-card envelope design on a traditional origami construction.
Initial Folds
Start with a 150mm x 112mm sheet of paper. Crease it in the middle then unfold it.Fold the top-right corner down the middle crease to form a triangle. Fold the opposite corner to the middle in the same fashion.
Make a parallelogram
Take one of the two unfolded edges ending with a 90° corner and fold in half to meet the next folded triangle. Repeat on the opposite side. You'll have what looks like a parallelogram with an extra segmentat each of the acute angles.
Form The Envelope
Starting with the corner you just folded, or the acute corner of the parallelogram, take it and fold to the middle at a 45° angle.
Repeat on the opposite side. Done correctly, you should end up with a rectangle with two chamfers.
Finish and Use
Take the sides that you just folded and tuck them into the tabs resulting from the previous step. You'll now have something resembling an envelope. To insert a letter, remove the paper out of the tabs, insert and refold.
