To start, I used some worsted weight yarn and an H hook. We'll make a simple multicolored medallion as our sample practice project. Begin by making a slip knot loop with your yarn,
Make as many chains you need for your pattern (here we will make 6),
With your hook still in the last chain, join the other end with a slip stitch.
It should look something like this...
Now we're ready to do the first round...our medallion will have double crochet rounds (your pattern may have something else). Work one double crochet in the center of the round like this,
Keep going, our medallion will have 12 dc worked in the middle of the circle,
When you're finished, close the circle with a slip stitch.
If you'd like your next round to be the same color, just keep going, but if you'd like to switch colors, just snip the yarn and pull the tail though that last loop.
Now you're ready to start the next round...
Tie on a new color. For our medallion, we're going to work two double crochet in each space all the way around...
Start by drawing the yarn through the hole and work a chain three, this will count as our first double crochet, work one double crochet in the same space, and two double crochet in each space all the way around...
Here's our medallion about halfway through...it is important to note here to crochet the ends in as you go along. This makes for a neater appearance and a lot less work later on.
And all the way around...close with a slip stitch.
Sometimes things in the round will have some kind of border or edging...to do this work your round in the same way...for our little medallion, we'll do a simple single crochet edging. Simply tie on a new color and work a single crochet in each space all the way around.
Here are some patterns that will help you practice crocheting in the round:
