brushes
Round Sables or Synthetics also called "White Sables"; #6, #8, #12, or #14. Robert Simmons Series #785 and Winsor and Newton Sceptre Series #101 are good. Flats: Winsor and Newton #965 excellent, 1" (1 1/2", 2") Rigger; #6, Winsor and Newton Series #860 or Robert Simmons #750. I use Winsor & Newton Series 7, #9, Isabey Kolinsky #8. The R. Simmons series gives very good results and is less expensive. Cheap Joe’s and Daniel Smith each have very good kolinsky rounds, I also use CJAS Dragon’s Tongue, #8, #12.

paper
Arches watercolor paper, 140 Cold Pressed (CP) good for outside work. (I also use 300lb and Rough.) Imperial size 22"x30" can be divided into 1/4 sheets or 1/2 sheets. I usually use _ sheets for outside. I make a “pad” of paper using 1/6 sheets about 10”x11” taped down on one side to a cut down piece of 12”x16” canvas board, to about 12”x10.75. ” Holds about 20 sheets. I mix up the paper, mostly, cold pressed and rough.

miscellaneous
Masking tape (artist's tape) or staples for gator board (regular stapler, not staple gun), spray bottle (empty hairspray is good), water container, soft pencils (4B, 6B), eraser (white Factis, soft), Kleenex, single-edged razor blade, natural "silk" sponge, "elephant ear" sponge, and a hairdryer are helpful.

easel
I use a Julian Half Box. Lighter versions, such as the Italian Portable Easel, Daniel Smith or Cheap Joe’s, are fine.

field box
I carry a small folding portable palette for table sitting, i.e., in a café.

portable stool
Bring what you have if you like. The Alvin Portable Stool in Daniel Smith is similar to one I have from L.L Bean.

umbrella
I have a small folding umbrella that is designed to attach to a beach chair. I attach it to my easel to give shade to my painting, but my favorite is to find a shady spot.
