I am making Cameron's Cap
for my son and I'm confused about this part of the instructions.
"Decrease section: Mark the stitch after each stitch marker with a safety pin. This will mark the center of each of the four double decreases. * Knit until one stitch before the marked stitch, dd; repeat from * around. Knit 1 round. Repeat these two rounds until 4 stitches remain."
I don't get the point of the safety pins. Will it not always be the stitch after the stitch marker? Why do I need the pins?
