I had tinkered around with crocheting when I was about 11 or so, which would have been around 1973. I had a cousin show my mom how to make the puff stitch. She was crocheting a six sided rug. For some reason I remembered that pattern in my head. I had no idea how to read patterns or what stitches were called at that time. I went home, asked my mom for some yarn. I played around with the yarn and made a small rug. That was about it for crochet, until I got older.
In 1983, I was expecting my second child and on bed rest. My mom started me off with crochet snowflakes, size 10 bedspread cotton and basic crochet stitches.
Crochet is a process that will continue after learning the basic stitches. I taught myself the rest of crochet through practice and learning how to read crochet written instructions and symbol instructions on my own. Back then we did not have video and I was not living close to family that could show me how the stitches worked and the meaning of abbreviations. It may take years to learn much of the basic techniques and language. Crochet is a continual learning process.
