i was watching the program the other day on pbs. you were dyeing fabric. and gave a formula or the amount needed for a 12 inch square of fabric.
then said that to dye a 24 inch square - you would need to double the recipe. just to remind you - that is incorrect. a 24 inch square has a surface a 4 times larger than a 12 inch square. and you would need to make 4 times the recipe of dye to obtain the same color and value for a 24 inch square as for the 12 inch square. ckquilter
Good catch, ckquilter. Thank you!

The amount of dye is usually based on the weight of the fabric to be dyed, (OWG) not the surface area.
Well, I'm not sure what process you're referring to, if you're painting rather than immersion dyeing, then the surface area calculation may be correct.
