Casa Isaac: Italian knitwear from G.R.P. Knitwear Mill
Casa Isaac is the knitwear line of Maglificio G.R.P., which has been working in Poggio a Caiano, Tuscany, since 1973. The name comes from Isaac's house in Bergman's Fanny and Alexander : a room full of objects gathered over generations, which is also how the label thinks about a knitted garment — something that stays, not something that passes with the season. The style is folk and country chic, with a recognisable balance between Nordic restraint and Mediterranean warmth. The yarns are natural — wool, linen, cotton, hemp, cashmere — and the runs are small by choice: every piece is made in Italy by the mill's own knitters, with work and finishing you notice up close, on the edges, the cuffs, the intarsia.
