About this weight
The traditional Aran sweater is a 16–18 sts / 4 in fabric crowded with cables, bobbles, and travelling stitches. The yarn was originally undyed báinín (cream-coloured) Galway wool, slightly oily so the sweater shed water on a fishing boat. A modern Aran-weight pattern will use 1500–2000 metres for an adult sweater — a substantial project.
Traditional Aran yarn is undyed cream wool from Galway sheep. Modern Aran can be any fibre at the same weight.

Swatching at this weight
An Aran cabled panel needs a 6-inch swatch including at least one full repeat of every cable in the pattern.
Swatch every cable panel separately; cables of different sizes consume horizontal stitches at different rates.
