So this is the first thing I've ever crocheted (is that even a word? I think it is? Google says it is - so it must be true!). My mum "taught" me to crochet on one dimly lit evening in France in the summer. I say "taught" because she'd only done one class (she's a knitter not a crochet-er (again - real word?)) and the lights really were dim so I couldn't really see what we were doing. So I feel confident in saying that if you have never picked up a crochet hook in your life before, you could make this mug warmer.
I have tried to provide a little stitch guide with step by step pics at the very bottom, which hopefully you'll find helpful. It's quite hard to take clear pictures of individual stitches, at least it is with my camera skills, but the text should help where the pictures fail, all being well. If you can't work it out just make the hot chocolate instead.
The original pattern is here - but I've added a few extra instructions to make it a little bit easier - I think. I ticked off each row as I completed it so I could keep track of where I was.
You will need: 4.5mm crochet hook 1 x 50g ball aran (US - worsted) yarn of your choice A button
First off the abbreviations: ch - chain dc - double crochet htr - half treble st(s) - stitch(es) ss - slip stitch
To fit a mug 7.5 cm (3in) diameter across the top (but remember wool stretches so my mug is a bit bigger and it stretched over just fine.)
The directions: Make 32 ch. Row 1: 1htr in the third ch from hook (each chain makes a v shape - so count three v shapes back from your chain and insert your hook into the middle of that v). Then work 1htr in each ch to the end. (You'll now have 30 sts)
Row 2: 2ch (this allows for the height of your stitch so that the sides of your mug warmer are straight and neat). 1htr in each st to the end of the chain (Don't start in the 2ch you've just made at the beginning of the row but in the first stitch in the row).
Row 3: 2ch, 2htr in the first st . Then 1htr in each stitch until the last stitch - then 2htr in that final stitch. (The 2htr in the first and last stitches allows you to increase the row - you'll now have 32sts)
Row 4: 2ch, 2ch, 2htr in the first st. Then 1htr in each stitch until the last stitch - then 2htr in that final stitch. (34 sts)
Row 5: 2 ch, 1htr in each st.
Row 6: 2 ch, 1htr in each each. At the end of the row, do not turn, make 8 ch (for your button hole) then ss (which basically means attach the chain - see stitch guide) approx 1cm (1/2 in) down the side of your work.
Edging: Spread 4dc evenly along that edge of your work, 3dc in the corner st (to turn the corner), 30dc along the bottom edge, 3dc in corner st, 5dc along second side edge, 3dc in corner st, 1 dc in each st across the top, 1 dc in each ch around the button hole, ss into first dc adn fasten off (tie a knot to secure your work and snip the thread).
To make up: Sew the side seam up to the top of the mug handle. Sew on your button to correspond with your button hole (maybe choose a button that is slightly smaller than mine). The snuggle your mug up inside and do up the button.
So that's the pattern - it sounds complicated but once you get going it really isn't. The stitches are fairly simple too.
Start with a slip knot
Yarn over your hook
Pull the loop on the hook over the yarn to create a stitch
Repeat as many times as needed ie 30ch - means make 30 chain - so do it 30 times.
Half treble (htr)
Yarn over your hook
Insert your hook into the stitch or chain you want to work.
Yarn over again
Pull the yarn through the stitch (you now have three loops on the hook)
Yarn over again and pull through all 3 loops.
It doesn't look like much to start with but once you've done a couple you'll see the stitch pattern taking shape.
Double crochet (dc)
Insert the hook in the stitch or chain you want to work.
Yarn over and pull the yarn through the loop. You'll now have two loops on the hook.
Yarn over again and pull through both loops to create a double crochet (again you'll need to work a few to see the pattern.)
Slip stitch (ss)
I couldn't get clear pictures of this - any I took made it more confusing and it really isn't. Starting with one loop on the hook (probably the one you just worked), insert your hook into where ever you want to join (so in the case of our mug warmer you want to join your chain for the buttonhole to the main work to make the button hole). Yarn over Pull the yarn through all the loops on your hook. Repeat as required.
