A few years ago I needed a large painting for hanging over our fireplace for the Studio Tour. At the time we didn't have one up there at all and it was about time. I decided to go long, vertically, since it would fit better. I made up 3 feet by 6 feet stretcher bars out of 2x4's cut down to 2"x 2" bars. I stretched canvas over it and began painting a scene of a sycamore tree up off the road to Nojoqui (no-ho-wee) Falls from a reference photo I had taken. I liked the original painting...looked good and fit what I needed it for. More importantly, it was the best I could do at the time. Things change.
If I painted this one all over again I'd do it much differently now. This was my largest painting at the time and painting larger is different. You need bigger brushes and you need to practise painting with bigger brushes. I would use even larger brushes if I painted this one over again now. I think that would make you feel as if you were still working smaller but on a larger scale of course if that makes any sense.
