This is one of the things I was hoping to accomplish with this list -
compiling a collection of standard (or not so standard) sculptures.  I
was hoping to find the time (and software) to take the stuff I have
written up so far and draw real pictures that could easily be exchanged
through e-mail (in postscript).  I suppose paper is always an option
though.  I just forget those things sometimes.  As far as just a
collection of single balloon animals, there are a bunch of small books
that I was given to look through.  Dewey and Seigel are two names that
come to mind.  None of them are what I think you're looking for.

I'm not sure I agree that a notation would be sufficient without
pictures, but I'm willing to try.  Here are some basics.  The names I've
used are what I've heard them referred to.  I started writing this up a
while ago before encountering any decent books on balloons and have used
bits and pieces of this to explain how to make a few animals.  While I
wouldn't think of it as much of a notation, it should at least help to
define a few terms.  Just about everyone on the list now already knows at
least the basics of balloon sculpting, but this should also help anyone
just trying to get started (I hope).  All comments, complaints,
suggestions welcome.

pinch and twist -
---------------

forming an animal amounts to making bubbles of various sizes and then
twisting them together in different combinations.  Forming a bubble is as
simple as pinching the balloon and twisting so that the pinched area
stays pinched without your fingers.  Well, this is almost true.  The
balloon will untwist unless some kind of locking twist is used to secure
it.

			pinch and twist

locking twists and the basic four-legged animal - If three bubbles are
made using the method described above, the second two can be twisted and
locked together.  The hardest part of this is learning to use all of your
fingers to hold bubbles that you've made until they get "locked".
	   ______________  ____  ____  ____
	--(______________)(____)(____)(____)=
			 1  a  2  b  3  c

In the above picture, the numbers refer to the twists, the letters refer
to the bubbles.  To secure all of these bubbles, fold the balloon at
twist 2 so that 'a' and 'b' sit alongside each other.  Now form another
twist combining 1 and 2.  This is already the basic head of an animal.
'a' and 'b' are ears.  'c' is a nose.

This same process can be repeated two more times to complete a basic dog
(or whatever you wish to call it).  That is, immediately below the head
make three more bubbles and twist the second two together.  This forms a
neck and two legs.  Now, the same way, form a body and two more legs.
All of the twists in the balloon look like the figure below.

apple twist
-----------
This can be done with any balloon, but if you do it with asmall, round
balloon you can actually form something that looks like an apple.  This
can be great for a William Tell routine.  I'll try to describe it on a
small balloon first.  Blow up the balloon part way and tie it off.  Push
the nozzle end into the balloon with one finger until it is inside the
tail of the balloon.  With the other hand grab the tail far enough in to
grab the nozzle also and give it a few twists.  this should stay on it's
own.  You should now have something that basically forms the shape of an
apple with a stem sticking up.

This twist has a lot of uses aside from just making apples.  In any long
thin balloon you can push the nozzle in and form a bubble with the nozzle
being further into the balloon than the twist.  When you release this it
should stay in the balloon without any other locking twists.

bird body 
---------
Any figure that has wings or arms needs those wings and arms to sit
alongside the body.  To form this we will make three bubbles and do the
locking twist above, but make the second two significantly longer than
the first.  This will be a head and wings.  Make another bubble roughly
the same size as one of the wings and push only that bubble completely
through the wings.
	   ________  ______  ______  ______  _
	--(________)(______)(______)(______)(_)=
		   1  body 2  wing 3  wing 4 

The wings should be twisted together.  When the body gets pushed through
them, 1 and 4 will be locked together even though there is no twist
between them.

pop twist
---------
It is often desirable to get more limbs on an animal than there are ends
of the balloon.  The basic dog works out ok, but legs need to be grouped
in twos.  The pop twist will allow two legs or arms to be separated.
Twist two medium bubbles, three small bubbles, then another medium
bubble.  Do a lock twist with the medium bubbles so nothing untwists.
        __
       (  )  <-
      // \\  <- Three medium bubbles
     (a) (b)
       (c)    <- 3 small bubbles

Ear twist bubbles a and b.  Twist them about 5 times each (completely
around).  Now pop c.  The air should not come out of any of the other
bubbles.


toes
----
I'm not sure what anyone else calls this one so for now I'll call it a toe
twist since that's what I like using it for.  Make an ear twist, with only
a little air in it.  The softer the better.  Twist the bubble in half
now to form two toes.
