All you need to do is follow this simple rules:
1. Start with the right number of stitches
If you start with too many stitches your work will become wavy, and if you start with too few your work will bunch up into a cup.
The taller the stitch you're using the more stitches you need to start with:
- If you're crocheting with single crochet start with 6 to 8 stitches.
- If you're crocheting with half double crochet start with 8 to 10 stitches.
- If you're crocheting with double crochet start with 12 to 14 stitches.
The number of stitches you start with may vary depending on your tension and the yarn you're using.
2. Increase evenly on all rounds
Increase the same amount of times as the number of stitches in your first round.
Have the same number of stitches between the increases throughout the round.
For example, if you're working with single crochet and started with 6 stitches your work will look like this:
Round 1: 6 single crochets into the Magic Ring (6st)
Round 2: increase on all stitches (12st)
Round 3: (1 single crochet, 1 increase) x 6 (18st)
Round 4: (2 single crochet, 1 increase) x 6 (24st)
Notice how on every round there's one more stitch between the increases, and how the total number of stitches at the end of each round keeps increasing in multiples of 6.
And that's all you need to know to crochet a flat circle with single crochet, half double crochet and double crochet! Use this technique when you want to make crochet flowers, bags, bowls, mandalas and even some amigurumi pieces where you want the finished project to stand upright!
