Here I've created a simple line drawing showing the key elements that you need to produce. You don't have to create them in any given order, but using the line drawing, I've tried to let you see the basic parts needed in order to construct the 3D horse figurine.
I've tried to make this as simple as possible.
The body consists of the chest, back and rear of the horse.
The neck and head (add the ears separately).
The legs (add these after neck and head).
The tail.
The ears.
Put these elements together and you'll find the horse figurine will take shape (Please note that this figurative plan is not in 3D).
The body of the horse figurine is made up from two balls of crumpled paper, of roughly equal proportion, taped together to form the basic central structure of the figurine.
The neck and head are formed in a similar way, with the neck being a more tubular form. As I mentioned in my previous post, play around with the angle in which you attach them to each other and the central body of the figurine.
Now create the legs by using a combination of short tubes of rolled up paper and fan shaped folded paper. Use the fan shaped folded paper to create the upper leg muscles.
The tail of the horse is simply a short piece of paper folded to roughly the correct shape of a tail. Fold the paper a number of times to give it added strength.
The ears of the horse are created by using the same folded fan-shaped paper technique. Again keep in mind the visual proportion in relation to the rest of the figurine.
I hope you've found this helpful, but if you do need more information don't hesitate to contact me further.
