The "L" Matrix is
the only one of the four frameworks that starts out
resembling the shape of the finished sculpture character. As
you load balloons, it will automatically take on proportions
that make it considerably closer to the official logo shape.
The left side of
the "L" framework has a single protruding loop. Use
that loop to wrap around one of the balloons on the lower
curve of the "D". That will join the two letters and
set the tilt angle between them to match the official logo.
I found 3.5" (89 mm) to be my
preferred inflation diameter for making the "L". We suggest
you start there and then adjust to suit your needs.
You may download a layout for making a template to use from
layouts for both a slightly larger and a slightly smaller
circle as well.
