Like the shark, the walrus is categorized as "hard/intermediate" due to instruction extrapolation (taking marked directions from one flap and applying those same folds to another unmarked flap) and the number of minute folds (too small to indicate on the paper) required to make a realistic product. Particularly after folds 7 and 8, minor adjustments are required but there is no good way to show it on the instruction sheet. Instead, common sense, trial and error, experience, and a higher difficulty rating will have to suffice.
Following the directions exactly will produce this:
But comparing this to the completed patterns below, you will notice many small discrepancies: 1. the color and curvature of the tusks, 2. the crown of the head has been rounded and often glued together, 3. the flippers and lower shoulders are often folded an extra time or rounded, 4. I had to inset a penny into the posterior most of these walruses (walri?) to keep the animal's balance back, otherwise they tend to fall forwards onto their heads. These and other modifications are strongly encouraged.
I had to have at least one psychedelic walrus, for fairly obvious reasons. (Also notice the flippers have been folded an extra time.)
My 8 March 2013 blog about origami prompted me to launch a second blog, one dedicated solely to origami. This way, as I complete instructional sheets, I can post them directly to this blog and it will not interfere with my Beatles blog.
