For me, the constancy and repetition of crochet helps to settle my mind into a relaxed state. I spend a lot of time looking for patterns in stitch counts, creating perfectly symmetrical and even designs, and counting, counting, counting each individual stitch.
Photography, too, can thrive on patterns. Continuity can create structure in a photo, just as a break in an expected pattern can create drama and lead the eye to the focal point of an image. Use pattern and repetition today to draw your viewers in.
