This is a lovely, simple hat to crochet. No more than an evening's work. I've made two already and I'm trying to find an excuse to make more! It works up quickly on a 5mm hook using Rico Essentials Merino Aran - a bit of a favourite of mine at the moment.
Each round is worked in a different colour. I kept to a straightforward four-colour sequence, but obviously you could vary this as you please. It is worth noting, that with this pattern the colour you choose for Round 2 is also the colour the rim of the hat will be if you continue in sequence.
Each new round of colour is started with a standing stitch and Rounds 1-4 are worked as a granny hexagon, with the increases being worked into the corners each time.
The following instructions are to fit a child. This fits all three of my children age (just) 3, 4 (nearly 5) and 7 (and a half!). I have included instructions further down the page on how to adapt this hat to fit an adult.
Child's Bobble Hat:
To start: Ch6 and join with a slip stitch (ss) to form a ring.
Round 1: Ch3, 1tr into ring, [ch2, 2tr into ring] 5 more times. Join to top of ch3 with ss and fasten off.
Round 2: Starting in any chain space (ch sp), [2tr, ch2, 2tr, ch1] 6 times. Fasten off yarn.
Round 3: *[2tr, ch2, 2tr,] into corner ch sp, ch1, 2tr in next ch sp, ch1, repeat from * 6 times. Fasten off yarn.
Round 4: *[2tr, ch2, 2tr,] into corner ch sp, [ch1, 2tr in next ch sp, ch1] twice, repeat from * 6 times. Fasten off yarn.
Round 5: Starting in centre of one side, *[2tr, ch2, 2tr,] into ch sp, [ch1, 2tr in next ch sp, ch1] 3 times, repeat from * 6 times. Fasten off yarn. (Ignore the corners, it will all start to look a bit uneven at this stage... this is fine, don't worry!)
Round 6 - 12: Continue straight for 7 rounds, working [2tr, ch1] into each ch sp around. Fasten off yarn.
Round 13: Decrease round, work 2tr into each ch sp around. Fasten off yarn.
Round 14: 1dc in each stitch around.
Round 15 - 17: Ch1, continue around alternating front post dc (fpdc) and back post dc (bpdc) to form rib pattern. Fasten off yarn and weave in ends.
Yarn over, pull through and work as you would a normal dc.
Similarly, inserting the hook for bpdc:
The rib pattern starts to tighten the brim of the hat; to make it looser work fewer rows and to tighten work more.
And that's it! Weave in all the ends, add a lovely big velvety pom pom, and it is ready to go.
Now I just need to choose the colours for the next one...
p.s. Dec 2104 - I'm writing up the grown-up version of the pattern and will post a link to it here soon...
