Heartbeat Spectrum // Resonant Pattern | Valentine's Day Greeting Card · Seasonal Collection

from $6.99
Heartbeat Spectrum is a study in rhythm and connection. A visual translation of pulse into pattern, this design uses layered color bands and harmonic repetition to suggest resonance between two frequencies. It is romantic without being literal, expressive without relying on clichés.

Printed as a folded greeting card on premium stock and paired with a matching envelope, this piece is meant to be held, opened, and kept. The interior is blank, leaving space for language that matters more than decoration. This card works equally well as a Valentine’s message, an anniversary note, or a quiet statement of connection.

Designed with architectural precision and emotional restraint, Heartbeat Spectrum belongs to the Seasonal Collection as a modern expression of affection.
