So the cosy season is finally upon us. This is my absolute favourite time of year to be crocheting. I am all about chunky knits, blankets and anything to make me feel warm and cosy. Today I’m sharing a crochet pattern for this simple hot water bottle cosy…

I love a hot water bottle in winter and in fact they are used here all year round (particularly useful for that time of the month!) I first created a version of this cosy for an issue of Simply Crochet Magazine several years ago now (issue 11) and I’ve made it many times since then so thought I would share it here.

It uses a very simple pattern of double crochet and treble crochet (UK) to make a lovely texture. I’ve totally given in to my love of tweed for this pattern but you could easily make this with any aran weight yarn and experiment with stripes or block colours. I’ve added a ribbed collar to this one which gives enough stretch to be able to easily insert the hot water bottle – just make sure you put it in empty! 

As always there is an inexpensive ad free pdf version of the pattern available on Ravelry or Etsy if you prefer to print your patterns.

I hope you enjoy it, any queries please feel free to email me (all my details are in the ‘About Me’ section of this blog).

Hot water bottle Cosy

Yarn:

Yarn A: 1 ball King Cole Big Value Tweed Aran (100% acrylic, 100g/257yds/235m) shade 1751 Berber – 65g used

Yarn B: 1 ball Bergere De France Twiste Aran (52% wool, 48% acrylic, 50g/80m/87yds) shade Rubis Orange – 35g used.

Yarn Alternatives:

Approx. 100g of any aran weight yarn should give similar results.

Hook: 5.5mm (I/9)

{ You can shop my favourite tools here }

Gauge:

13 sts and 11 rows of stitch pattern (dc, tr) to measure 10x10cm (4x4in) using a 5.5mm hook.

Measurements:

Cosy should fit a standard Flashy 2 litre hot water bottle. I find the cover has a good amount of stretch but if you feel like you need to make it wider just add to the starting chain in multiples of 2 (includes a turning chain) so you keep an odd number of stitches in row 1 and add extra rows as needed.

Stitches/Abbreviations used:

st(s) – stitch(es) 

ch – chain


sl st – slip stitch 

dc – double crochet  (US = sc)

tr – treble (US = dc)

Special Stitches:

Rtrf – Raised treble front (US = Fpdc – Front post double crochet)

Rtrb – Raised treble back (US = Bpdc – Back post double crochet)

Pattern notes

*Pattern is written in UK terms*

The texture in this cosy is created by working a double crochet into each treble crochet from the previous row and a treble crochet into each double crochet. Each row should begin and end with the same stitch. If a row ends with a double crochet, then the turning ch-3 counts as the 1^sttreble of the next round. If the row ends with a treble then the turning ch-1 is not counted as a stitch and a double crochet is worked into the last treble of the previous row.

The cosy is worked in two pieces, which are then joined along the sides and bottom. The collar is then worked in rounds along the top of the cosy.

To join

Place both pieces together and working from the top of the cosy rejoin yarn A around the side of the post of the last stitch. Double crochet evenly through both pieces around the sides of the cosy, joining as you go (working through the loops of the foundation chains around the bottom of cosy). Leave the top unworked for opening.

Collar

Rnd 2: 3ch (counts as 1tr) 1tr in each st around, join with a sl st to top of beginning ch-3. [34 sts]

Rnd 3: 1ch (does not count as st) 1rtrf in tr directly below (the beginning ch-3 of rnd 2), *1rtrb, 1rtrf; repeat from * around, join with a sl st to top of first tr. [34 sts]

Rnds 4 – 16: Repeat rnd 3 until collar reaches approx. 14cm (5.5”)

Weave in ends. Fold collar down and keep cosy!
