My maternal Grandmother mainly, and her sister helped too. I was probably around 7yrs old. My Grandmother gave me my first hook and a ball of yarn and sat with me teaching me the basics.
After stopping in my teens and almost forgetting what I was taught, I relearned how to crochet when I was 27 by myself, as I was pregnant with my daughter and on a doctor-ordered semi-bedrest at the time and needed sometimg to occupy myself. My MIL had a hook, a ball of yarn, and some magazines that I "played" with trying to remember what I was taught 20yrs before. After my daughter was born I started getting books and expanded on what I was taught when I was a child.
