Four outlines: a circle, a heart, a ribbed pumpkin and a six-armed snowflake. The pattern is built inside the outline rather than stamped onto it, so motifs bend to follow the silhouette and every shape stays whole.
That is what makes the seasonal pages work. A pumpkin mandala is a Halloween page without a drawn pumpkin, and a snowflake mandala is a winter page without a drawn scene — no illustration is involved at any point.
Every outline is a closed loop, so a fill tool cannot escape through a gap when colouring digitally, and on paper no line reads as an accidental break.
