Something artists do not like to think of when making art is how much is how much is it costing me to make art? Granted I spent most all of my travel budget to London, Amsterdam and Paris on paint in the London Windsor and Newton store on a trip years ago and still have one or two of those tubes left. Other than that I am always buying new paint.
So for me it's about $1100. in supplies on hand at all times.
Paper: $50 worth of full watercolor sheets on hand
Paint: Watercolor professional grade Windor and Newton
$450 worth of watercolor tubes are always on hand. Much of watercolor painting involves putting pigment down and then removing some or nearly all of it while still wet- not very eficient but that’s how it is.
Paint: Acrylic professional grade larger tubes
$214 worth of large tubes on hand
Color pencils
$150 worth in Prismacolor pencils. Iindividual pencils cost $1.40 each.
Watercolor Brushes
$150. in watercolor brushes on hand (some are dead and just keep for the memories)
Acrylic/Oil Brushes
$80. In acrlic/oil brushes on hand
Other stuff I am using during painting process- papertowel, soft erasers, vine charcoal, pencil, digital camera, computer, prints of photographs.
