Traits

• Stamped causes simple shapes to appear. There are some restrictions on these shapes - both due to previously-existing genes, and to keep the gene properly shaped and simple. These will be listed a bit later in the guide.
• Stamped should be lighter or darker than the base coat.
• It can be hard-edged or lightly textured. It should not be soft-edged or heavily textured.
• It has no minimum, but should be noticeable on the design.
• The shape can repeat, but it should be the same shape throughout the design. It can be solid or hollowed out, and you can use both of these presentations in the same design.

Shape restrictions:

The following shapes are not allowed:

• Quadrilaterals - Squares, rectangles, diamonds, and the like. These can be made with the Squared gene.
• Pentagons, Octagons, Hexagons, or similar shapes. These can be made with the Hexagon gene.
• Shapes that are solely made up of lines. (This does not mean shapes that are hollowed out - those are fine, and in fact, are an important part of this ruling!) A shape used for Stamped should be thick enough to hollow out.

Additionally, shapes should not be overly complex:

This fleur-de-lis is considered too complex. Each piece parses as a separate, unique shape of its own due to the spacing of the sides and the shape/distance of the bud from the rest of the shape.

This fleur-de-lis can be considered the maximum complexity for stamped. The shape is nice and compact and parses as a unified shape. The bud flows into everything else.
