Let's say we are making something, say, a picture, and we want to set up (prepare) the basic things such as the size, the material, the shape and the color of the canvas. Or if we are making a wooden figurine, we want to prepare a piece of wood of an appropriate size and color.
Is there a single word to describe the process of setting up those? I thought about "styling", but it occurs to me that "styling" has a slightly different meaning, more like "developing the design concept" or something.
If it is impossible to say it in one word, what would be the shortest phrase to describe that?
