"Tranquility" is 48x60", acrylic on canvas, and it came out of nowhere.  I was not expecting it.  I was under-painting a canvas in green to do a forest scene.  I thought it might be interesting to experiment with texture so I used a tool typically used to do faux-wood imagery (like a comb).  I applied the base coat thickly and pulled the comb through.  In places the paint had dried enough to kind of pill up, resulting in a surface that looks almost like linen.  This effect was so appealing to me that I followed the painting in a completely different direction, minimal, textural, and for me, very tranquil.  I get pleasantly lost in this and it brings me peace.
