Tutorial on how to make triangles is here
Fold all needed triangles.
Make a body and don't forget for turned around triangles and 2 holes on the bottom for legs insertion (8th row from below to top).
Add neck and with some triangles shape the head. From one orange triangle make a beak and draw 2 dots on the head for the eyes.
Roll 2 orange papers in the tube and assemble orange triangles and insert the legs into the holes in the body until they reach the triangles on the other side.
Balance body with the legs and your stork will stand itself.
