|These hats are made in carreaux crochet. Since crochet is not quit flexible it contains two tubes for elastic.
|The basic is a border in the size of your head, getting larger as soon as it is the right height. Plus an open circle that you attach to the border.
The black and white version in this example is made with Azurite (Distrifil) - 50 gr ~ 140 m, I have used around 70 gram of each color. With 80 stitches I got a circumference of about 57 cm.
|You start with chain stitches, in this case 80 + one to turn. Then 3x a row of single crochet. Put a marker or a clothpin in the loop.
Start with the other color in the first chainstitch (see end of the white yarn in the picture) and make 3 rows of single crochet stitches.
|Fold together. Use stitch markers through both colors, in this case every 8 sts. In between I made 3 sc back on black / chs / 2 sc front on white / chs / 3 sc back on black.
In my blog you can find a basic explanation of this new crochet technique.
Finish the last cs with the loop of the other color - see images. And make the same row with this color.
|A second row made 'color-on-color'.
|After these dots follows the second tube. 3 rows sc with white, 3 rows sc with black.
Then again some dots with black, last stitch finished with the white loop. And this row repeated with white.
|When the border has the height of the front you start increasing stitches. 6 per row when you make single crochet stitches, 12 when you make double crochet stitches.
|The upper circle is started with two open circles. Start with a magic loop or 3 chain stitches and then 6, 12, 18 sc and if you wish one more of 24 sc. Attach them with stitch markers to mark where you will increase in the next round. Make a front/back row with one color (black in the picture) and finish the last stitch with the loop of the other color.
Continue your open circle with single or double crochet. In case of sc increase 6 per row, in case of dc increase 12 per row. You can work in rounds, but it's more challenging with the color changes.
Another possibility is to continue with the border piece when you feel it is wide enough and decrease towards the top.
Be sure to end with the same number of stitches on the border and the circle.
You might want to use dots with the same distance to make it easier to attach both parts later.
|Close both sides of the circle with a tapestry needle. Be sure not to go to both layers.
|Close the border the same way, but be sure NOT to close the two tubes. You might want to put a pencil in to remember ...
|Attach the border to the circle.
You can either use yarn and a tapestry needle or work them together with croceht stitches, like sc in the border, ch, sc in the circle, ch etc.
Again, avoid working through both layers.
|Put elastic in both tubes and tight the ends with a knot. Hide the knot in the tube. If you give this to someone show them how to get out the knot if they want to make the elastic more tight.
