One loom, six metres in length, currently dominates the great, light-filled weaving hall of Edinburgh’s renowned tapestry workshop, Dovecot Studios. At its side sits Master Weaver Naomi Robertson, threading yarn from countless dangling bobbins between and around taut vertical strings, each dabbed with tiny, code-like markings. The tapestry, which is growing slowly upwards from the base of the loom, forms a spread of pinks, reds and golds, shifting horizontally through rich tonal ranges.
