Quality of the product's surface treatment and texture, visually and tactilely

Harmony of the product's colors and finish layers to serve its aesthetic unity

Quality of joining the product's parts and concealing or intentionally revealing joints

Proportion of the product's parts and sizes to create a balanced, beautiful form

Offering a solution or design that sets the product apart from the market's repetition

Unifying recurring details across the product to show coherent mastery

Designing the product to fit the user's body and motion comfortably

Drawing on a craft heritage or local identity authentically without appropriation or kitsch

Tight joints and a piece that holds functionally: the joint bears load, the vessel doesn't leak, the structure doesn't loosen.

The cleanliness of the work's last five percent: surface, edges, finishing — what separates the amateur from the maker.

Discipline of axes, measurements, and repetition; intended symmetry or its intended breaking.

Conformance of Islamic ornament / Sadu to its geometric rules: the grid, closing repetition, star symmetry.

Quality and honesty of documenting the making stages and the soundness of their craft sequence, not the result alone.

Treating the material per its nature: wood expands, clay shrinks, metal expands with heat, thread tensions to a limit.

The form serving its declared function, or a clear decorative intent, without ornament feigning a function it can't perform.

Centring the clay mass steadily on the axis before forming — the base of every balanced ceramic piece.

Even wall thickness from base to rim, a sign of control and material efficiency.

The piece's soundness after firing: no cracks, blisters, or warping, with mature colour.

Applying glaze uniformly without clumping, bare patches, or running.

Even stitch size, direction, and spacing across the whole work.

Tuning thread tension so it neither puckers the fabric nor leaves the stitch loose.

Matching the repeated pattern units in size, spacing, and alignment.

Fidelity of the motif to traditional Sadu rules in units, colours, and symmetry.

Tight wood joints (mortise-tenon, dovetail) without gaps, holding without relying on glue.

Working with the wood grain's direction, not against it, and using it aesthetically.

Flat wood surfaces with a finish smooth enough to be felt by hand before the eye.

Clean, tight solder joints without gaps, excess, or burns.

Symmetry of the metal piece's axes and precision of its repeated measurements.

Polishing metal through grits to a uniform, scratch-free sheen.

Straight, regular hand saddle-stitching with even hole spacing and angle.

Burnishing leather edges to a smooth, rounded, uniformly coloured finish.

Precision of the Islamic ornament grid and the symmetry and closure of its repeat.

Even carving or engraving depth across the pattern so light and shadow are uniform.
