Stave and rune structure
A Viking piece reads first as a deliberate construction: eight stave arms on one hub, a rune row with even rhythm, a knotwork weave with a followable path, or a figure or ship with a clear silhouette. Stencil viability comes from that construction holding together at final size, not from carved texture, photo shading, or dense background fill.
Check: Name the construction in one line, then confirm its skeleton at true size. If stave arms drift off radial order, runes crowd into uneven slots, knot strands lose their path, or the figure or hull loses its outline, repair the structure before judging detail.
