Equalizer Blanket

First of all, you need to know how to crochet a solid square:

Abbreviations:
American English: DC = double crochet
[British English: TR = treble crochet]
This pattern is in American English terms, the British terms are in [brackets].

An important note about corners:
I've used a DK weight yarn. This is lighter than a worsted weight yarn, so I created my corners by crocheting two DC [TR] + two chains + two DC [TR] into the corner space. If you find that your work is bunching or curling, it is possibly because your yarn is heavier or your tension is tighter. One way you can correct this is by only crocheting one DC [TR] into your corner spaces, i.e. one DC [TR] + two chains + one DC [TR] into the corner space.

Start by chaining 4, then join with a slip stitch.
Round 1: 
Chain 3 (counts as the first DC [TR]), do 2 DC [TR] into the ring. Chain 2, 3 DC [TR], chain 2, 3 DC [TR], chain 2, 3 DC [TR], chain 2 and join to the third chain of your first 'fake' DC [TR] - like this:

Round 2:
Chain 1, do 1 DC [TR] in the same stitch below. Crochet 1 DC [TR] in next two stitches, *in corner space crochet 2 DC [TR] + 2 ch + 2 DC [TR], then crochet 1 DC [TR] in the next three stitches.**Repeat from * to ** twice more. Join with slip stitch to the top of the first DC [TR].

Round 3:
Chain 1, do 1 DC [TR] in the same stitch below. Crochet 1 DC [TR] in next four stitches, *in corner space crochet 2 DC [TR] + 2 ch + 2 DC [TR], then crochet 1 DC [TR] in the next seven stitches.**Repeat from * to ** twice more. Join with slip stitch to the top of the first DC [TR].

Round 4:
Chain 1, do 1 DC [TR] in the same stitch below. Crochet 1 DC [TR] in next six stitches, *in corner space crochet 2 DC [TR] + 2 ch + 2 DC [TR], then crochet 1 DC [TR] in the next eleven stitches.**Repeat from * to ** twice more. Join with slip stitch to the top of the first DC [TR].

Round 5:
Chain 1, do 1 DC [TR] in the same stitch below. Crochet 1 DC [TR] in next eight stitches, *in corner space crochet 2 DC [TR] + 2 ch + 2 DC [TR], then crochet 1 DC [TR] in the next fifteen stitches.**Repeat from * to ** twice more. Join with slip stitch to the top of the first DC [TR].

Round 6:
Chain 1, do 1 DC [TR] in the same stitch below. Crochet 1 DC [TR] in next ten stitches, *in corner space crochet 2 DC [TR] + 2 ch + 2 DC [TR], then crochet 1 DC [TR] in the next nineteen stitches.**Repeat from * to ** twice more. Join with slip stitch to the top of the first DC [TR].

Chain two, yank tightly. Leave a long tail for joining, and cut yarn.

Now, the bad news...

(Yarn needed is given as an approximate amount. I was virtuously using scraps, so these amounts are approximate and represent the maximum amount I used.)

You need to crochet:

• 9 turquoise squares* (75g yarn)
• 17 green squares (150g yarn)
• 14 yellow squares (120g yarn)
• 11 orange squares (100g yarn)
• 6 red squares (50g yarn)
• 51 black squares + edging on other squares (1100g yarn)

* If you want to make a slightly longer blanket, crochet 18 turquoise squares, not 9!

Lay your squares out as per the diagram above and sew them together. I edged the blanket with a round of DC [TR] in black, then a round of SC [DC] in a contrasting colour (I used turquoise) and finished it off with another round of DC [TR] in black.
