Understanding these principles could be helpful when designing knitting projects in the Fair Isle, Intarsia or Modular styles. It's an area of expertise common in textile design but not generally covered in knit design. I have found many Knitters to be obsessive about symmetry. Some won't knit shawls and scarves with the scalloped pattern stitches that are offset at the cast-on and bind-off edges. They will instead knit two panels bottom up or top down that are joined at the center back. I remember talking to a friend who had tried to do a Feather and Fan pattern that way and discovered that the ends can't be easily joined at the center due to the offset. She had given up on the project for that reason. She was surprised when I mentioned that my solution to that is to create a "resting" panel at the center. You could do a ribbed section for a scarf or a wide garter stitch section on a shawl. The width of the panel required would have to be tested by swatching.
One of the reasons that I use the crochet cast-on technique on exposed edges is that is visually the same as the standard bind-off and is therefore symmetrical as well. I've used it when making lengthwise scarves as well the more standard version. It can also be used on garments that are knit side to side when they have no separately knit borders.
Asymmetrical designs tend to create strong reactions in the observers. I've always liked that type of design but I know that it disturbs many people. The artistic view is that asymmetry creates visual movement and that symmetry can be visually static. I took a course with Kathryn Alexander many years ago. She does not care if her garments are symmetrical so it was interesting to see how many members of the class reacted negatively to those garments. What do you think is symmetry a must for your garments?
