If you have ever made something that looks like these,
then you already know how to fold today’s first triangle. (The image comes from recipegirl.com. You can find her recipe for Spinach, Feta, and Sun-dried Tomato Phyllo Triangles here. I haven’t tried them, but they look delicious.)
The paper version looks like this.
Take a piece of letter paper and fold it in half lengthwise.
Open the paper flat again, and fold the bottom right corner of the paper up to meet the vertical crease. The bottom left end of the new diagonal fold should start at the bottom left corner and the fold should look like the image below.
Unfold your paper, then re-fold along the vertical crease.
Fold the bottom right corner up so that the folded edge matches the diagonal crease. (See the image below.)
Fold the bottom left corner up and to the right so that the former lower edge matches the vertical fold on the right side. (See below.)
Fold the bottom right point up to match the left edge. (Again, see image below.)
Fold the top corners in and down to match the next picture. (This will look slightly different if you are using A4 paper.)
Fold the upper section down over the lower triangle.
Here’s where we depart from the phyllo triangles: take the upper portion you just folded down and tuck it into the pocket.
There you have your equilateral triangle letter fold. (The diagonal fold from the second step will appear again tomorrow in the instructions for folding a hexagon. Practising today’s triangle will make tomorrow’s hexagon easier.)
The second triangle is a right-angled one, and quite simple. Take a sheet of letter paper and fold the top right corner down and to the left. The former top edge of the paper should match the left hand side of the page.
Take the top left corner (indicated by yellow pointy finger in the image above) and fold it down and to the right. The yellow pointy finger in the image below shows where that corner should end up.
Fold both bottom corners up and in as shown below.
Fold the bottom section up, and tuck it into the pocket in the top triangle in the upper section.
There! Your second triangular letter, this time a right angled one. Neither of these will go through the post, but they might be nice to enclose in presents (or lunches) after writing a message first. They could also be used to wrap small flattish objects. The first might make a good CD wrapper, though you would have to scale up your paper size.
If you would like to try a third triangle, I posted a Valentine’s day version here.
Tomorrow’s hexagonal letter fold is another good one for enclosing flattish things. (If you want to wrap something flat to send through the mail, you could always go back to the Regency fold I demonstrated in this year’s first Advent post.)
