Did you know that you can make crochet rows without the foundation chain? Here's the tutorial. I've made it with double crochet (US term), but it can easily be adapted to any stitch size.
1. Make 3 chain stitches.
2. Yarn over and pull a loop through the first chain (just like if you were making a double crochet stitch).
3. But in stead of finishing the double crochet stitch, pull another yarn through the loop closest to the tip of the hook, to make another chain stitch.
4. Then finish the double crochet stitch like normal.
5. You now have double crochet stitch with an extra chain at the bottom.
6. Yarn over, pull loop through the extra chain, pull yarn through this loop and then finish the double crochet stitch. Repeat this until your row is long enough.
Now we are starting to see a pattern, right?
Here's what a (small) no foundation chain row looks like.
And here are example swatches of no foundation chain and foundation chain. The pattern above is no foundation chain. The pattern below has foundation chain.
