So, I’ve done the Pull-Tab Note and Letter-to-Envelope folding tutorials. Here’s another way paper or letter folding tutorial to add to the list. Yes, these were the real things that kept me busy back in the day. Haha!
Start out with a rectangular sheet of paper.
Fold the sheet in half, crosswise.
Unfold. Take the bottom corner, and do a dog-ear fold towards the center crease.
Turn the sheet around, and repeat with the opposite corner.
You should end up with a parallelogram like this.
Next, fold one of the open edges towards the dog-ear fold.
Do the same with the opposite edge.
You should end up with something like this.
Take one of the corners, and fold towards the center (where the dog-ear folds meet) and tuck under the side folds.
This is what it should look like when the corner is tucked under.
Repeat on the other side.
Tuck the corner neatly as well.
