We can often save time and create a different kind of texture in our sculptures, by creating very open patterns with 260's and then filling the holes with other balloons. What makes this fastest is that filling of holes doesn't require any twisting.
Using this approach, it's also possible to create effects that would be extremely difficult through only twisting. For example, creating pictures within a large sculpture can easily be accomplished by stuffing balloons of different colors into a basic gridwork.
