I was taught to knit by my aunt in my teens. When I decided I wanted to learn to crochet my aunt was very far away and I couldn't get to her.
I asked a friend, who crocheted, over and over to teach me but she always said she was too busy, later, maybe later.
I got tired of waiting so I bought a hook that came with a one page flier showing the chain (which was the only thing I knew), a sc, hdc, dc, and triple. That was the entire flier.
So I sat down to teach myself. Within a week I had designed my own pattern for hats for my kids, and was making them hats scarves, and had figure out from an old pattern in a magazine how to do the ripple stitch.
After that last my kids started to get afghans, and doll afghans.
My friend finally decided that maybe her help was needed. So she would look at my work, find a mistake, rip it out handing it back saying do it over.
I fast learned to find those mistakes before my friend came to visit. No more starting over.
That was 24 years and many many projects ago.
