Locking diamond Letter

This was my preferred letter fold in school, but since it took me a while to remember how to do this I figured I'd make a tutorial so I don't forget again, and also share the knowledge.

Start with a regular size piece of paper 8.5in x 11 in fold in half long ways or hot dog

Here is your hotdog/long ways fold

Fold one corner on the diagonal to make a square

look at that nice crease

fold it again diagonally the other way, then flip it over

This is how your diagonal creases should look when it's flipped over

fold the top down so that it's in the middle of where the diagonal creases intersect, then flip over again to the starting side

see how that crease from the backside it allowing the paper to fold up into a triangle? That's what happens when you fold it from the other side.

press the triangle down flat

squish

take one of the corners & fold it up to meet the point at the top.

fold the other side to match, then rotate the paper to start on the other side

diagonal fold on side

make sure to crease it to help it stay

diagonal fold the other side, then flip over

now fold the top down again so that it creases where the diagonal folds meet

Make sure to crease, then flip over

once again admire the way it's trying to fold in already & flatten it down

nice flat triangle at the top

fold the edge to the top on both sides

cool, from here we'll tuck these folds under, this will help to make the interlocking part of the envelope.

tuck 1 side under the diamond

tuck the other side under so one is a diamond & the other side is 2 triagnles

flip it over

fold your triangle down, this helps the letter stay together

fold the other side down.

feed the folded triangles into the diamond to lock your letter together

enjoy your cute letter!
