Rope dyeing is one of the most important dyeing methods used in classic denim. Not all denim is rope-dyed. However, when the project values a vintage-style fade, a ring-dye (core-white) structure, or three-dimensional aging patterns, rope dyeing becomes a critical choice. This article introduces how rope dyeing works and how ALLBLUE considers dyeing design as…
Most classic denim fabrics are twill weaves. However, not all twills behave in the same way. The direction and structure of the twill line affect how denim looks, feels, twists, and fades over time. This article introduces the main twill constructions used in denim and how ALLBLUE considers weave structure during fabric development. Right-Hand Twill…

Kojima is home to over 200 denim-related businesses. Within Japan’s various denim regions, that figure stands out. What is more striking is not just the count, but the structure: weaving, dyeing, sewing, vintage finishing, washing, and final processing — the entire denim value chain — fits within a few kilometers. Anatomy of the Kojima Cluster…
In the quiet space between jobs, we keep sketching a few fabrics in our minds. The air of an old vintage piece, and a pair of jeans for every day. Both of them we hope to make someday.
When most people hear the words “indigo dyeing,” they imagine a simple process — fabric submerged in a vat of blue dye. In practice, what happens inside an indigo vat is closer to microbial fermentation than to dyeing. And it is precisely here that Japanese selvedge holds a kind of scarcity that cannot be transplanted.…
When work gets heavy, we lay out an old pair of jeans and spend some time simply looking at them. A baton of trust, passed down through decades of wearing.
Premium selvedge production has globalized. Looking at verifiable industry statistics, this piece traces the structural shift, what scarcity Japan still holds, and how ALLBLUE positions itself in the new landscape.
A long-time neighboring workshop quietly closed down. A production region cannot stand on a single workshop alone. Yet those who remain must carry the work forward.
