Felted pieces are more ridged, longer lasting, and more structured than traditional knit pieces, making the process ideal for creating customized, comfortable slippers. And better yet -- they are easy to make because they are knitted in a similar way to socks, only oversized -- with large needles and then felted in the washing machine. In Knitting and Felting Slippers, authors Sabine Abel, Annette Diepolder, and Karoline Hoffmeister guide you through the process to create 23 charming felt slippers for adults and children with well-detailed techniques, step-by-step instructions, and finishing details including heel seaming and cap heeled slippers. Once the slippers have been knitted, the washing machine does the rest of the work. The hot water and agitation cause the fibers to become matted and shrunk to the appropriate size.
