Seigaiha Fabrics

Seigaiha (青海波) translates to “blue sea waves.” The pattern originated in Persia, traveled the Silk Road, and became iconic in Japan through gagaku court dance. It symbolizes endless good fortune and the eternal flow of prosperity. Read the complete history.

Seigaiha’s flowing curves contrast beautifully with angular patterns like asanoha or kanoko. Pair with solid indigo cotton for balance, or combine with sakura florals for a traditional Japanese aesthetic.

All seigaiha fabrics in this collection are 100% cotton, printed in Japan. Most are medium-weight quilting cotton (110-120 gsm), ideal for bags, quilts, and home décor. Some specialty items use dobby weave or shantung texture for added visual interest.

Yes! Seigaiha is beginner-friendly because the continuous wave pattern is non-directional. You can cut pieces in any orientation without worrying about pattern alignment. Start with simple projects like knot bags or cushion covers.

The most iconic seigaiha uses indigo blue on white or ecru backgrounds, echoing ocean waves. However, modern interpretations include red, black, mustard, and even multicolor variations while maintaining the traditional wave structure.

Machine wash at 30°C on a gentle cycle with similar colors. Our Japanese cottons are colorfast and pre-shrunk, but avoid harsh detergents. Iron on medium heat while slightly damp for best results. Store away from direct sunlight to preserve color vibrancy.
