When looking at fabrics, an interior designer will focus on these characteristics.

What are your choices?

My choices are

shape and form

space and color

color, texture, and pattern

proportion and emphasis

But i think it would be color, txture, and pattern ?

Shape and form/space and color/proportion and emphasis of what? The rooms? The fabric only.

This is a terribly broad question ... or else it's answered quite specifically in your text.

What do you think?

If the question means that he/she is considering only the fabrics, I think you're right.

Yes she/he is considering only fabrics.

shape and form also color
