8 identical wedges repeat around the centre, across 3 concentric rings, giving 63 separate shapes to fill. At a relaxed pace that is roughly 47 minutes of colouring.
The outline is a six-armed snowflake, so the design reads as winter while still being a symmetrical pattern rather than a picture.
Lines are thick and the shapes correspondingly large, which is what crayons and young hands need: a shape has to be big enough to fill without going outside the line.
Every outline is a closed loop. On paper a broken line reads as a mistake rather than a boundary; colouring digitally, a fill tool escapes through any gap and floods the page.
