3D Model: Long-Tipped Brushes
This image shows the brushes, in 17 sizes, with each of two texture variations.
This image shows the brushes without any additional levels of subdivision.
When looking for some brushes to make that would be suited more towards calligraphy than, say, oil painting, I ran across a few brushes in this style and decided to make a selection to choose from for my images.
