Getting started with the crane fold
Most people jump right into folding without checking their paper first. A standard 15cm x 15cm sheet of kami works fine for your first try, but once you've done a few dozen cranes and your fingers get faster, you'll want to move up to larger squares or thinner tissue. The problem is that thinner paper rips at the mountain folds if you're not careful with your creases. Start with the colored side facing down. Fold the square in half diagonally, bring the corners together, and press flat. That gives you a triangle. Fold it in half again and you should see a small triangle roughly a quarter of your original paper size. Unfold everything so the paper lays flat again. Now take the bottom corner of the triangle and fold it up to meet the top point. Turn the paper over and repeat on the other side. What you're building is called a bird base, and you need both sides to match closely or the rest of the fold chain will skew left or right. I used to spend twenty minutes trying to force mismatched sides into alignment, then realized I was starting the base wrong from the very first diagonal fold. The fix was simple: make sure each valley and mountain crease went through the full thickness every time instead of just scratching the surface.
With the bird base laid out, you'll see two flaps on each side. Fold the outer edges of the front flaps toward the center line on both sides, then unfold. Do the same with the back layer. Turn the paper over and fold the whole triangle tip down about halfway to create the neck and tail guidelines. Inside reverse fold the top point. Push the paper open gently from the bottom and tuck the tip inward between the layers. Repeat on the other side for the second point. You should have a long diamond shape pointing upward with two triangular tabs at the bottom. These become the tail and the neck depending on which one you choose to elongate first. Fold one corner tip down into a narrow triangle for the tail. Then fold the other tip upward at a shallower angle for the neck. Make another inside reverse fold on the neck tip to curve it downward slightly. The head should point at roughly a forty-five degree angle from the body. Same thing on the tail side, though usually just a single reverse fold instead of two.
The wings come from the two wide panels on either side of the body. Fold each wing outward at a slight angle. If your paper is stiff, score the fold line lightly with your thumbnail first so it goes down cleanly. A properly made crane sits balanced on its belly without tipping, which means your symmetry work early on actually matters. Misaligned wing folds will make it list to one side and stay that way no matter how much you adjust later. Common pitfalls worth knowing Beginners tend to pull too hard when doing the inside reverse folds and tear the paper at the fold line. The paper fibers break if you bend past ninety degrees too quickly. Bend slowly to about sixty degrees, then ease it the rest of the way. If your paper is thin, score both sides of the fold before attempting the reversal.

Another issue is the final inflation step. Some tutorials tell you to blow into the small hole at the bottom to puff out the body. That only works with thin paper like tissue foils or Chinese gold leaf paper. Standard origami paper needs you to gently pull the wings apart while applying light pressure to the chest area from underneath. Don't yank the wings or the body will split open at the seam. I once spent an hour trying to figure out why every crane I made had a lopsided head. Turns out I was creasing the bird base diagonal first, then folding the triangle corners up in the wrong order and skipping the second valley fold entirely. My cranes looked like ducks with crooked necks. Now I count three distinct valley folds and two mountain folds before moving past the base formation stage. It adds maybe forty seconds to the fold time but eliminates the guesswork. If you want a reference sheet to keep next to your workspace, search for the standard 1977 Japanese original crane diagram. The Asahi Square diagram by Akira Yoshizawa is the version most hobby stores reproduce, and it comes with step numbers that match the folding sequence exactly. Downloading a high resolution version saves you from squinting at a phone screen while trying to align a tiny corner.
The whole process takes about five to seven minutes on your first attempt, closer to three minutes once you stop second guessing the reverse fold angles. Paper choice matters more than most guides admit. Twenty pound kami gives you sharp, clean creases that hold shape. Eight pound tissue tears on the neck reverse fold every third crane. Stick with the heavier stuff until your muscle memory handles the thin paper without complaint.
