I was looking through the selection of brushes at my local art store (feeling how soft some of them were- I like to do that) and every time I reach the end of the aisle I always gawk at how much some of the expensive brushes cost. Some of the small oil painting brushes were around 30-40 dollars, while the bigger ones around 100. They had watercolor brushes that cost that much as well.
It gets me wondering, why are these brushes so expensive? Are they pulled from wild unicorns? Humor aside, I don't possibly see a reason for brushes costing 70-100+ dollars. What's so special about these brushes? Do they do something that "normal" expensive brushes don't? I mean, I like to use sable brushes for painting, but I can't imagine why anyone would spend that much on a paint brush. Is there something I'm missing?
