Mosaic knitting patterns play with two-colored grids and overlapping lines, which predestines them for easy op art interpretation. Single slipped stitches (worked in the main color) form vertical interruptions to a background of simple horizontal stripes that alternate two rounds each of a main color and a contrasting color. Ludwig Wilding (1927– 2010) used similar effects in his retrospective exhibit Visual Phenomena.

In this sock design, named after Ludwig Wilding, the vertical lines that the slipped stitches produce are arranged in chevrons that travel to the toe of each sock. This simple pattern is ideal for beginning sock knitters.
