Last week I finished the lovely cowl in the photo above and found myself with a spare ball of yarn so I thought I’d have a go at designing a one ball crochet hat pattern to match it and this is what appeared!! It’s quite a flexible hat and can be worn as a beret or slouchy beany.
Crochet hats are very tricky, particularly when it comes to sizing as so much depends on your tension as well as the type of yarn used. I’ve found the best approach is to be flexible: be prepared to undo a few rounds and adjust as necessary. This pattern is very adaptable because the top part is meant to be slouchy and you can then adjust the number of decreases in the rim to make it fit you perfectly. So if possible try it on yourself or the intended wearer as you get towards the end.
For the more mathematically minded there is actually a formula you can use to work out sizing which involves the use of pi. I never thought I’d find a use for that in my grown up life! Measure the circumference of the hat wearer’s head (pulling tape measure tight), then divide by 3.14, the result in cm is the diameter that the crown of the hat should be.
So… circumference divided by 3.14= diameter of crown in cm. Increase until you reach this diameter (in my pattern we increase until the end of round 4) then you are ready to start repetitive rounds of single trebles.
But for the non mathematically minded trial and error is also effective! My hat pattern makes a medium/large hat, approx 59/60cm (yes, I’ve got a big head!) There are various strategies you can use to make your hat smaller: I would suggest trying a smaller hook eg 7 or 8 mm and you will probably find the need for more decreases on the rim (notes in pattern). If you find you need a much smaller hat you can also adjust my pattern by finishing the increases at the end of round 3.
Here’s a link to a hat sizing chart which you might find helpful if making the hat as a gift – hat sizes uk.
You could also try it with aran weight or chunky yarn instead of super chunky to make a child’s hat. Child’s hat sizes can be found here.
Here goes, have fun!!
PS If you are interested in making the crochet cowl to match I will be sharing that pattern in the next couple of weeks- it uses 2 balls of the same yarn so you might want to buy it at the same time as buying your hat yarn! Link to buy yarn in pattern..
One 50g ball of super chunky yarn (make sure it is at least 96m)
button to decorate
Tension – approx 9 tr to 10cm (when increasing)
Abbreviations: tr= treble, dc = double crochet, dc2tog = join two dcs together by putting hook through stitch and pulling yarn back, hook through next stitch, pull yarn back (3 loops on hook), yarn over hook pull through all 3, this joins two stitches together to make one and is called a decrease
Chain 6 slip stitch to first chain to make a ring
Round 1 chain 3, make 11 trebles in the ring and join with slip stitch to third of chain 3 (12 stitches)
Round 2 chain 3, make a treble in same place as slip stitch, 2 tr in every stitch around, join with a slip stitch to third of ch 3 (24 stitches)
Round 3 chain 3, make a treble in same place as slip stitch, *1 tr in next stitch, 2 tr** in following stitch, repeat from * to ** around, finishing with a single treble, join with a slip stitch to third of ch 3 (36)
Round 4 chain 3, make a treble in same place as slip stitch, *1 tr in each of next 2 stitches, 2 tr in following stitch ** repeat from * to ** around, finishing with a single treble, join with a slip stitch to third of ch 3 (48)
Round 5 chain 3, 1 tr into every stitch around, join with slip stitch to 3rd of 3 ch (48)
Round 6- 8 chain 3, 1 tr into every stitch around, join with slip stitch to 3rd of 3 ch (48)
Round 9 chain 1, dc into every stitch around, join with sip stitch to chain 1 (48)
NB at this stage try the hat on, or measure, bearing in mind that we will be doing three rounds of decreases. It will feel loose but if the hat is feeling too loose you will need to add more decreases (dc2tog) so put fewer single dcs in between each decrease eg you could try 4dc dc2tog
Round 10 chain 1, *make 1 dc into each of next 6 stitches, dc2tog**, repeat from * to** until end of round, join with slip stitch to chain 1
Round 11 chain 1, *make 1 dc into each of next 6 stitches, dc2tog**, repeat from * to** until end of round, join with slip stitch to chain 1
Round 12 chain 1, *make 1 dc into each of next 10 stitches, dc2tog**, repeat from * to** until end of round, join with slip stitch to chain 1
Round 13 chain 1, make 1 dc into every stitch around, join with slip stitch to chain 1
Fasten off, weave in ends and decorate with a button of crochet flower.
For an extra vintage look wear with your favourite old fashioned coat (or is that a step too far?!)
Hope you like the pattern, I’d love to hear how you get on!
