Is it normal for crochet to curl?
The most common reasons crochet edges curl is because tension is too tight (gauge is off), the foundation chain stitches are too tight, there are not enough stitches crocheted in the round, and increases or decreases are inconsistently crocheted in the round.
How do you keep yarn from curling?
The most well known method to prevent curling is by blocking. How do you do that? When you’re finished knitting your project and you’ve bound off your stitches, put your garment into tepid water with a bit of pH neutral soap. Let the wool soak for about 30 minutes, but don’t rub!
Does using a bigger crochet hook use less yarn?
If you are using the same pattern (same number of stitches and rows/rounds), a larger crochet hook will use up more yarn. If you are going for the same size of project (say a 36 by 36 inch blanket), a larger crochet hook will use up less yarn.
