In Stuart Jeffries’ review of Arcadia (11 March) he wonders what the Scottish women are wrangling on a table. The answer is they are “waulking”, finishing newly woven tweed by soaking it in stale urine, then thumping it rhythmically to shrink and soften the cloth. In the Scottish Gaelic culture the process was accompanied by singing and clapping. Although traditional waulking is disappearing, four waulking groups – Edinburgh, Strathspey, Barra and Laxdale Ladies – still compete in the Royal National Mòd, which supports and develops all aspects of the Gaelic language, culture, history and heritage.

• Brought up in Derby, the local form of address was “mi duck”or “mi ode” (Letters, 7 March). When living in Plymouth I rather enjoyed being “m’lover”. In both cases the form of address was not differentiated by gender.
