It starts almost by accident: the women who buy their knitting needles and wool from Georgia Walker's little yarn shop linger for advice, for a coffee, for a chat and before they know it, every Friday night is knitting night. And as the needles clack, and the garments grow, the conversation moves on from patterns and yarn to life, love and everything. There may be different ages, from different backgrounds and facing different problems, but they are drawn together by threads of affection that prove as durable as the sweaters they knit.
