I'm new, and new to knitting. Can you help me read part of a pattern? What do the  brackets mean? Here's the context: Dec row K1, [k2tog, yf, skpo] 22 times. 67 sts. Cont straight until back measures....etc
It's directing you to repeat the bit between the brackets 22 times, so you'll k2tog, yf, skpo 22 times.
Fear the Sock Monster! RAWR!
The individual has always had to struggle to keep from being overwhelmed by the tribe. If you try it, you will be lonely often, and sometimes frightened. But no price is too high to pay for the privilege of owning yourself. ~Friedrich Nietzsche Double Pointed - a knitting blog
