@Kaderin: It is hard to estimate the material costs besides the canvas because I use so little of the paint on the sizes I have made so far. Like I use a little blop of paint but was it 1/100th of the tube? 1/10? I dunno! Same with the flow medium. It cost about 7 dollars for the bottle but how much of the bottle is going into each painting is a mystery to meee. Aaany way:

Reusable supplies:
A tube of paint is about $3.50-ish
The flow medium was $7 for the one quart bottle
Tap water for thinning is negligible

Single use supplies:
A dollar a piece for the glass I was using (not sure how big they are cuz I don't remember 5x7 at the largest maybe?)
1.55 for an 8x10 canvas board
80 cents for a 6x6 canvas board
1.60 a piece for the stretched canvas I got but they were crap so not sure about selling them.

@Mekatra: There are but I tend to get puddling with them since I suck at knowing how close or far to be from my painted surface cuz I am awful at everything.

@Den The obvious solution is to rob a random little girl's toy box.
