Price formula for commission work with pastels. 

Length of paper x Height of paper /2 

total number + material cost (determined by paper brand and size) = your price.  ( note: rounded to the nearest dollar) 

example: 

9x12= 108

108/2= $54 

$54+ $30.60 (material cost) = 84.60

total fee $85.00

With frame: $85.00 + 25.00 = $110.00 

Pastelmat paper size prices without a frame.

7x9.9= $45.00

9x12 = $85.00

12x15.5 = $130.00

19.5x 27.5= $310.00

27.5x39.5= $600.00
