Shagging is a hundreds-of-years old technique, used by hand knitters in New England and Canada, to make hand knit mittens warmer. Robin Hansen described this technique well in Homespun Handknit and in Flying Geese and Partridge Feet and shows mitten patterns using the technique. I haven't seen the technique used on slippers or slipper socks, though, and thought it was ideally suited to the purpose. The shagging adds a cushy, inner layer to the slipper sock, further protecting the feet from any cold drafts. The socks are easy to knit and the shagging is fun and quick to do, after the socks are knit. I've worked up this pattern in 6 sizes, covering children through men's sizes. Now, what makes these slipper socks scrumptious? The yarn - Brown Sheep Lamb's Pride Worsted, used double - it is so soft and cozy. I've used 2 colors together in each of the samples, for a marled effect - some are bright, especially the children's socks, others are muted and earthy. Lamb's Pride comes in a wide array of colors, so choose the two you like best!
