I have been knitting - dresses for baby dolls. The large doll is a normal size dolls house baby doll who is 7cm long while the little vintage plastic one is only 5 cm long (or 1 1/2 inches long in the old scale). Over the years I have bought a tub-load of very fine wool and silk/rayon threads on large cones originally intended for machine knitting but they make great knitting wool for dolls house size garments. The large dolls dress was fiddly but nothing compared to the small one. Her dress is knitted in a silk/rayon thread not much thicker than sewing cotton. It was the sleeves that presented me the most challenge as they were knitted separately and then sewn into the armholes later. I guess she can be a big doll for the dolls house girl doll to play with.
