Blue BlueIndigo Book (Sashiko)A6 Size (fits Planner and Original)

  • 2024 New

This cover is brought to you by a collaboration with Seilin & Co. denim brand Blue Blue.



In the early 1980’s, Blue Blue debuted as a maker of denim shirts. They focused on the color indigo blue and denim that transformed over time with extended use. This cover combines durable denim Blue Blue material with traditionally crafted “Sashiko” material so users can enjoy the two different textures together.



This diamond-patterned sashiko fabric was historically used to make clothes. The embroidery is greatly detailed with a high thread count.







When you open the cover, you can see the Indigo German Cloth that Blue Blue is famous for. It’s a strong, resilient material also used in military jackets.







The pen hook on the inside is designed to hold a pen by its clip. The cover retains its nice form even when closed.







The two navy bookmarks use sturdy material.







The button has a subtle, almost black color and is carved with the Blue Blue emblem. It gives a satisfying, low click when you open and close it.







The back of the cover has a large pocket with the Blue Blue tag that is perfect for temporary storage such as tickets or postcards. Keep it with you and it’s like having a partner by your side.



*From the Hobonichi Techo 2024 lineup, the Original book is available as the Japanese edition and the English edition.
(The English edition is only available as the January start version.)



About BLUE BLUE

An original brand by Seilin & Co. with a strong focus on denim and indigo blue debuted through the Hollywood Ranch Market lineup in the early 1980’s. It includes shirts, pants, jackets, and other denim apparel designed as simple and basic daily wear.

A cover full of unique charm

We previously worked with Blue Blue in 2016 to create a techo cover, and we’ve got a new one coming out together in the 2024 lineup.



Last time, our cover was made with horse leather that was dyed indigo blue. This time we’ve completely changed it up with material decorated with elaborately embroidered Sashiko textiles. This material had been carefully stored for a long time, as it had previously been used in clothing but was set aside with the intention of finding a good use for it. The A6 and A5 size covers both use diamond patterns, but the textile in each size uses different techniques and thread density.



Importantly, because these covers use materials and techniques that have been dearly cherished by Blue Blue, we’re confident that they faithfully represent the comfort and reliability of Blue Blue’s clothing line.



Examine the cover with your eyes and your hands, and enjoy the feeling you get when it fits comfortably in your hands.
