Sweater Keychain Crochet Pattern

Give someone a hug and let them know you’re thinking of them with this cosy sweater keychain crochet pattern. I’ve also included a couple of options for printables to make gifting easy.

Crochet stripey purple sweater keychain.

Have you started thinking about Valentine’s Day yet? If you’re looking for something different or you’re just not that into it, I’ve got you covered. This pattern is so quick and the colour combinations are endless. The instructions below are for the stripey sweater but you could easily make it in a single colour and pop a little heart on the front or other embellishment – how cute would that be?? It’d be a fun one for kid’s to give to their friends or just to let someone know that you’re thinking of them.

You can find all the instructions for creating the keychain and assembling the card down below. Please check your gauge and use the correct materials to help ensure that your keychain hangs in the right place on the card. Enjoy!

  • DK weight yarn in 2 colours – main colour (MC) and contrast colour (CC) (I used Paintbox Yarns Cotton DK in Pansy Purple/Pale Lilac and Lipstick Pink/Blush Pink)
  • 2.5mm crochet hook
  • Keychain (I used a 1″ keychain ring with a 1.25″ chain)
  • Stitch marker
  • Yarn needle
  • Scissors


  • ch – chain
  • sc – single crochet
  • hdc – half double crochet
  • hdc-inc – half double crochet increase
  • hdc-dec – half double crochet decrease
  • sk – skip
  • sl st – slip stitch
  • st/s – stitch/es
  • […] – repeat the instructions in brackets
  • (…) – indicates stitch count at end of round


The pattern is written using US terminology and measures approximately 2″ x 3.5″ (5cm x 9cm) when using the materials listed.

The body of the sweater is worked in joined rounds from the top down. The sleeves are added at the end and are worked in a continuous spiral without joining.

The ch 1 at the beginning of each round does not count as a stitch.

If you are using this pattern in conjunction with the printable cards, please use the materials listed above. Use the gauge measurement below as a guide and adjust hook size as necessary.

Gauge = 1.5″ after R3

Colour changes take place in the last yarn over of the previous colour, the joining sl st is made in the new colour. Keep the unused colour attached and carry it up the inside of the sweater.

If you’re giving your keychain as a gift, you can download the PDF printables below.

There are two different designs and you can choose between a full size foldable card or a single sided half card (the single sided card prints two to a page).

(I recommend using a ruler and Exacto/X-Acto knife (or other craft knife) for precise cutting).

  • Save the PDF file to your PC.
  • Print the template onto a piece of A4 card. Make sure to select actual size and that your paper size is set to A4.
  • Trim off the two short edges, cutting just inside the black lines.
  • Fold the card in half matching up the edges and using the fold lines as a guide. (If you’re using the single sided card, do not fold. Simply cut using the centre cut lines as a guide).
  • Open the card out and trim off the two long edges.
  • Take a piece of yarn or twine and thread it onto a sharp needle. Poke the needle through the lowest of the two marked dots at the top of the card from front to back.
  • Thread your keychain onto the twine left on the front of the card. Thread that end onto the needle and poke it through the other marked dot.
  • Tie the ends together in a bow on the inside of the card and trim off any excess.
