1.

Does the carpet use a one-knot detail? If not, then it might work on some larger scale, but the smallest scale is being wasted.

2.

Are the individual colors interesting in themselves, and are they justaposed so as to enhance each other?

3.

Are the smallest elements defined sharply by using contrast in both color hue and gray scale value?

4.

Are the smallest elements simple and symmetric in shape? (triangles, squares, and diamonds - no blobs)

5.

Is every element coupled to a contrasting element of the same size that has complimentary qualities?

6.

Do intermediate and larger elements show the maximum number of internal sub symmetries?

7.

Is every internally complex element balanced by a plainer surrounding shape that has a coherent shape?

8.

Is a random spacing of similar elements balanced by a regular, highly structured region of about the same size?

9.

Do elements and interposed spaces of all sizes link to each other through similarity, symmetry and scaling?

10.

Do different elements have sizes that define a descrete hierarchy with ratios approximately 2.7 between consecutive levels?
