Acrylics are perhaps the most versatile painting medium and can be applied to just about any surface. Acrylics can also mimic more traditional media, including oil paint and watercolor.
The only real weakness, as far as acrylics go, is that a brush must remain wet or all its hairs would soon stick together, as acrylics dry very quickly. Of course, carrying a bunch of brushes outdoors is kind of a drag, so a palette knife is much more of an alternative.
The first painting was done during a slack time, while being too tired or too lazy to go fell walking. A short ways from the Lake View Guest House is a semi-private trail along the Rothay, and it has always been relaxing to paint there: one palette knife, a bunch of paints, canvas board, and something to drink.

The second one, a much larger painting, was done at home from some quick sketches I made one morning before the start of a fell walk. The day had begun with a thick morning mist which the sun was in the process of burning away. Across lake Grasmere, the morning fog had just lifted from the water surface.
For working across broad areas in thin (or very wet) paint, I prefer a paper towel. Used too heavily, a paper towel soaks up too much of the paint, but with a light pressure, the towel can add a texture or effects all its own.
