at right angles. However, mosaic knitting has limitations relative to other techniques for producing color patterns in knitting such as Fair-isle knitting. Depending on the pattern, a mosaic-knit fabric may be stiff and tense, due to the many slipped stitches; such fabrics may be better for coats and jackets, which do not require as much drape. The tension in the fabric may also distort the rectilinear lines into curves. These problems may be overcome by judiciously elongating the stitches. Some color patterns may be impossible for mosaic knitting, if they require too many slipped stitches or if the colors do not line up conveniently (as described above). Blocks of solid colors can be done in mosaic knitting, but require many slipped stitches in a row; hence, blocks of solid colors are usually broken up with stippling, i.e., with regularly spaces spots of the opposing color. On the other hand, mosaic knitting is significantly lighter than Fair-isle knitting, which is nearly twice as thick and bulky. Long horizontal bars of the same color are also more convenient in mosaic knitting than they are in Fair-isle knitting (where such bars require that the other colors be held at the back for long runs). A simple extension of mosaic knitting is to use multiple colors, rather than just two, although the limitations on the pattern become even more severe. Another variant is to hold the yarns on opposite edges (or to knit circularly), which allows the knitter to knit only one row per color. References Bartlett, Roxana.
