What Is Tartan? A Guide to Lona Scott's 35+ Patterns

What Actually Is Tartan? (And Why Scotland Has 7,000+ Patterns)

The Scottish Register of Tartans lists 7,362 patterns as of this month. That's 7,362 distinct combinations of coloured threads, each following the same mathematical weaving principle that's been used in Scotland since the 16th century. Compare that to gingham (which has exactly one pattern: alternating checks) or plaid (an American catch-all term that technically just means 'blanket'), and you start to understand why tartan is its own category entirely.

So what makes tartan tartan? It's simpler than you'd think-and more specific.

The Weaving System Behind Every Tartan

Tartan is a twill weave where coloured threads repeat in the same sequence both horizontally (weft) and vertically (warp). That symmetry is the key. If you know the thread count-say, "K4 R24 K24 Y4" (4 black, 24 red, 24 black, 4 yellow)-you can recreate that exact tartan anywhere in the world. It's essentially a recipe written in threads.

This is why tartans can be registered and protected. Black Watch, for instance, has a specific sequence: blue, green, and black in precise proportions. Change even one thread count, and technically it's a different tartan. These patterns have been woven for generations, using the same thread-count formulas passed down through production records.

Why Clan Tartans Are (Mostly) a Victorian Invention

Here's the bit that surprises people: the idea that every Scottish clan has an ancient tartan is largely romantic fiction, courtesy of Sir Walter Scott and the 19th-century Celtic Revival. Before 1800, Highlanders wore tartan based on what their local weaver had available-usually determined by regional dye plants and wool sources, not family names.

The clan system as we know it today was codified in Victorian Scotland, when textile manufacturers realized they could sell more tartan by attaching heritage stories to specific patterns. Royal Stewart, now one of the most recognised tartans worldwide, was formalized for the Royal House of Stewart in the 1800s. Black Watch-originally worn by the independent Highland companies in the 1720s-became a regimental tartan. Buchanan, with its distinctive yellow and black sett, was assigned to Clan Buchanan during this same period.

Does that make them less authentic? Not remotely. These patterns have now been woven continuously for over 200 years in Scottish mills, making them genuinely traditional by any reasonable measure.

### What's the difference between cashmere and lambswool tartan?

Both follow identical weaving patterns, but the fibre changes everything about how the tartan wears. Lambswool (from a sheep's first shearing) has a 25-27 micron diameter, giving it a slightly textured hand and excellent durability-it's the workhorse of fine textiles. Cashmere, at 14-16 microns, produces a softer drape and lighter weight, though the pattern appears slightly less crisp because finer fibres catch light differently.

At Lona Scott, we weave both lambswool scarves and cashmere scarves in over 35 registered tartans, all woven on traditional twill looms. The lambswool versions start at £25, making them genuinely accessible-not everything in luxury textiles needs to cost a fortune. Our cashmere tartans (£65) use 2-ply Grade A cashmere, which means two fine threads twisted together for structure. Single-ply cashmere is softer initially but pills faster; 2-ply lasts years.

The Tartans We Actually Weave

We focus on the patterns people actually wear: Black Watch (that deep blue-green you see everywhere from Tokyo to New York), Royal Stewart (the red one everyone recognises), Buchanan, Dress Stewart, Hunting Stewart, and about thirty others. Some are clan tartans, some are regimental, some are district patterns from specific regions. You can browse the full collection to see how different colours shift the same weaving structure-it's quite satisfying once you start noticing the mathematical symmetry. Our heritage tartans collection showcases the most iconic patterns, and for something truly distinctive, we even weave traditional cashmere kilts.

If you're new to tartan, start with Black Watch in either cashmere wraps & stoles or a lambswool scarf. It's the most versatile pattern-works as a neutral, essentially-and it's the one you'll actually wear rather than save for special occasions.
