This is actually my long standing sketching kit, having undergone many changes yet remaining much the same. It is based around my small portable folding palette preloaded with colours, I experimented with the layout of colours but reached the current set up a few years ago now. Top Row are warm colours, and from left to right, Cotman Dioxazine Violet, W&N Alizarin Crimson, W&N Cadmiun Red, Cotman Indian Red, Cotman Yellow Ochre, W&N Lemon Yellow, W&N Cadmium Yellow, Cotman Gambage Hue, Cotman Raw Sienna, W&N Burnt Umber. Bottom row is the cooler colours again from left to right, Cotman Chinese White, Cotman Lamp Black, W&N Paynes Gray, Cotman Sap Green, W&N Viridian, W&N Phthalo Turquoise, W&N Phthalo Sapphire, W&N Cerulean Blue,W&N Cobalt Blue, W&N French Ultramarine These started out as mainly Windsor and Newton Artist’ Watercolours (in tubes & expensive) but this has given way to a few Cotman colours (also in tubes but affordable). Where transparency is not a characteristic of the colour I desire, such as in earthy tones like yellow ochre, I suspect the Cotman’s are just as good. For small/quick sketches the Windsor and Newton watercolours may be overkill anyway but they come into their own on good quality watercolour paper and larger works. I have been known to put this folding palette in my camera bag with a couple of brushes a small sketch book but kits one & two living permanently in the camera bags have made that unlikely now.
I carry the paints and media in a blue canvas folio. It holds my field drawing board, which has a appropriate sized nut glued on the underside so I can amount it on my camera tripod if a portable easel is required, but normally using it on my knee is fine. This board is just a bit larger than a quarter sheet of watercolour paper and I usually carry 4-8 sheets held in place for transport with rubber bands. I often have a sketch block or watercolour pad included, although I now like the idea of having a few post card sized pieces of watercolour paper as well. I sometimes finish a sketch, write a message on the back and post it (my post cards from Canada were popular with my family). I can also fit a full sized plastic palette and my canvas roll of my watercolour brushes. Its a pretty light setup and the canvas handles make this easy to carry. I usually also carry a full set of watercolour tubes in my luggage in a largish plastic screw top jar which can double as a water jar when needed, I seldom take these out sketching. The orange flagging tape is to make the kit easier to find in the field, whilst the blue is strong it can disappear when left in the shade, the orange tape against the blue is hard to miss.
I also still have my foldout studio always ready when I want to create a decent work place on the go. However this blue bag kit is what I will be taking in my luggage for most of my Endless Summer project trips.
