The design is based on the inner ring of a flower, which perfectly rotates on its axis. The petal segments draw nearer as the invite is closed. Each segment interlocks creating a continuous swirl. The circular petals are absorbent pores made from natural cotton fibres and saturated or outlined in a deep ruby red. The surfaces are engraved with symbolic peony, which represents love and affection. This invitation is called day and night to reflect the movement of a flower as the hours pass and night falls, delivering completion.
