The top illustration below creates what some demonstrators back in the day would refer to as a heart cable trim. The width of the strips of knit may vary, and the size of the holes need to be accommodated to suit the subsequent threading. The second illustration set results in a more traditional “pretend” cable. I-cord could be used for the second sample. Narrow strips of knitting will curl in however, and in many instances may be substituted for true i-cords. Because each pass of the carriage knits a row as opposed to slipping alternate rows, the knitting is twice as fast. In the instance below a series of holes are created for threading cording (or other chosen material)
The following illustrates threading option with a single length of the cording, which will need to be secured at each end with some stitching. Separate colors could be used on alternate sides for more color variation, and other threading sequences as well
