The Koi fish or ‘brocaded carp” (which it literally translates to) are domesticated varieties of the common carp. These are mostly ornamental and used for decorative purposes in ponds and water gardens. Another name for these are ‘Japanese Carp’.
The Koi are generally regarded as symbols of friendship and love and were developed in Japan in the 19th century. Many different colors and designs or patterns have since been developed over the years, with the most common colors being – red, yellow, black, white, blue and even cream.
This origami Koi I have folded, is from the book: Advanced Origami: An Artist’s Guide to Performances in Paper by Michael G. LaFosse. This model is my first try with the wet folding technique and I have come to see that the use of a little water to shape the model goes a long way in enhancing the final result!
I used an 8 ¼” sized square sheet of duo colored paper (animal print) for this model which gave the impression of ‘ fish scales’, too. The final model, when completed, is about 60% of the size of the original paper used.
If you don’t have such printed-paper, you can go ahead and use the solid colored paper itself. Try using colors in which the fish actually exist. You can choose to ‘paint’ the final model so that you have a few ‘splotches’ of reds or blacks or whites on your final model.
Once you have folded the model, you would need to shape it a bit. For this, it is recommended that you use a little water to round the edges of the body of the Koi as well as curve the tail. You can also use a little water to shape the ‘mouth’ and the whiskers or barbells.
