It is possible to take any of Kaffe Fassett's knitting pattern charts (eg from his Pattern Library book (2003)) and adapt them to make small or large square and rectangular items such as scarves, cushion covers and blankets. There is no need for shaping, but plenty of room for  experimentation, as here with the Gridlock Swatch. Kaffe's rather heartening motto is, "If in doubt - add twenty more colours".
