The book contains 52 knitting patterns for socks and slippers. The patterns feature a range of different techniques and textures, such as lace, cables, tuck stitches, colourwork, duplicate stitching and felting. All patterns come in 2 sizes. The book is suitable for both beginners and advanced sock knitters alike, as the difficulty level of patterns varies greatly. And as always in knitting (and in everything in life, really): you learn as you go.
