Loving the Blocking In

I started a new painting last night of a sand dune I watched all week long at S. Padre. In the late afternoon, the sun was low enough to make some great shadows and entice me into thinking I could paint them. I spent almost 3 hours last night at studio painting session, blocking it in. Not finished with the block in, but it already has a nice feel to it. And I love that it's another big canvas, 30x40", which works so well for using a palette knife. I've got a friend wanting to commission a really big painting of the Pennybacker Bridge. The subject matter sounds like fun; I just don't know what size to go for. My idea of big may not be his idea, so there will be some sorting out of the format and size. He's not been known to stay anywhere more than a couple of years, so a really large painting becomes a bit of an albatross when you have to pack it and haul it wherever you go. Which had me thinking that I might suggest doing it as a triptych so it's 1)easier to move and 2) can be hung seperately in different spaces if he moves to a place with smaller wall space. That would just be more challenging for me to do three complete paintings that can stand on their own. I might need another easel to keep all the works together. This is sure sounding like fun!!!
