I’m using up all my acrylic yarn by making hats. I like making hats; they are useful and crochet up quick. My go-to pattern is easily adjustable to any hat size. I’ve had it memorized for so long that I don’t remember where I first learned it, and now there are thousands of variations. So here is what I do (American notation):

Use a hook size recommended for the yarn you are using.
Row 1: Chain (ch) 2, 10 double crochet (dc) in a magic circle. Slip stitch (sl) in first dc.
Row 2: ch 2, dc in same stitch, 2 dc in each stitch around, sl in end of chain. 20 stitches in round.
Row 3: ch 2, dc in same stitch, dc in next stitch, 2 dc in following stitch, repeat, sl in end of chain. 30 stitches in round.
Row 4: ch 2, dc in same stitch, dc in next X (X=2) stitches, 2dc in following stitch, repeat, sl in end of chain. 40 stitches in round.
Repeat Row 4, increasing the X number each round. Make rows until the diameter of the circle is the hat size. (A size 7 hat has a 7” diameter. For hats for me, I found that my handspan is also my hat size.)
For the remaining rows, dc in each stitch, joining at the end of each round. You can make the hat as long as you like: to stop above the ears, over the ears, or roll up. Bind off.
