This is yet another model from the book – Origami Design Secrets: Mathematical Methods for an Ancient Art, by Robert J. Lang – which I have chosen to fold. It uses the technique of pleating to make the “shell” design on the shell of the turtle. It is advisable that a large paper be chosen to fold this model, as the pre-creasing requires a lot of folds and patience.

I started out with a duo-colored tant sheet of paper measuring 35×35 cms which I had purchased on Origami-Shop.com. The first 20 steps of the diagram constitute the pre-creasing and has a lot of small folds to be done. This pre-creasing turned out to be the most irritating part of folding this model. 😀

It took me absolutely ages to fold the pleats! Robert Lang in his book, lists out 2 options for creating the creases:

Option 1 – Folding the complete set of folds in order to pleat the shell. this would mean your paper will have numerous creases which will not be used in the end.

Option 2 – Folding a portion of the set of creases and marking out the rest using a pencil or pen.

I went in for option # 2 as I didn’t think I wanted to deal with ‘extra’ creases. I am quite happy with my first attempt at folding Robert Lang’s Western Pond Turtle, even though I can still improve on the limbs of the turtle.

I chose this model as I was pretty intrigued with the ‘pleating’ technique used by Robert Lang in folding this model, and I wanted to see if I could fold one which looked half as good as his exquisite version. 🙂 Hence, I am pretty pleased with the way it turned out in the end and am looking forward to folding more from his book.

I received the book – Origami Design Secrets: Mathematical Methods for an Ancient Art – last week and was eager to try out something from it. I chose this Lizard to start off with, as besides being less tricky, I have never folded any reptile so far.

This is a great book to have and I would recommend buying it, too, as the Author – Robert J. Lang – explains in detail how he has designed his various models as well as provides tips and ideas into designing your own model.

Paper to use:
This model will require a bit of wet folding, so it is better to select paper which is thicker than your regular kami. I selected duo colored green kraft paper which is thicker and makes wet folding easier. You can also use single side colored, too – you will have start with the colored side up in this case. The sheet I started folding with measured 10 inches in size (square).

This model is referred to as “lizard, opus 337” on Robert Lang’s website. The only diagram to this – as far as I know – exists in the book “Origami Design Secrets”.

This model has around 45 steps to complete and most of them are sinks. I would place this model as an intermediate level model.

The well-known Origamist – Robert J. Lang, has designed this Origami Turtle model; it can be categorized as intermediate in terms of level of complexity. The crease pattern / steps for this model is detailed out in the book – Origami Design Secrets: Mathematical Methods for an Ancient Art
– by Robert J. Lang.

What you need:
You would need a sheet of Origami paper measuring 7” or 8 1/4”. In this image, I have used Origami Paper Animal Prints 8 1/4″, by Tuttle Publishing.

However, one can also use single – side colored paper as well as wrapping paper (which is not foil like or very thin).

YouTube.com once again is the source for an instructional video for Lang’s Turtle. Mari Michaelis has taken the pains to record and share a very helpful and detailed video on folding the Turtle.
