Lightbulb Keychain Crochet Pattern + Card Printable

Give the gift of a smile with this fun lightbulb keychain crochet pattern + birthday card printable – who doesn’t love a good pun amirite?

I made this card for my son’s birthday at the end of October. He’s the card maker around here but I couldn’t very well get him to make his own birthday card. He loves puns so I knew that I wanted to include that and I loved the idea of combining the card with a gift. Sure I could’ve just stuck an applique on there but where’s the fun in that? So this keychain card was born.

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 yellow and grey (I used Paintbox Yarns Cotton DK in Mustard Yellow and Stormy Grey)
  • 2.5mm crochet hook
  • Black embroidery floss
  • Keychain (I used a 1″ keychain ring with a 1.25″ chain)
  • Stitch marker, yarn needle, scissors
  • Yarn/twine for attaching keychain to the card


  • ch – chain
  • hdc – half double crochet
  • hdc-inc – half double crochet increase
  • sc – single crochet
  • inc – increase
  • dc – double crochet
  • dec – single crochet decrease
  • 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 1.75″ wide x 2.25″ long (4.5cm x 5.5cm) when using the materials listed.

If you are using this pattern in conjunction with the printable card, please check gauge and adjust hook size as necessary.

Gauge = 1.25” after R3.

Colour changes take place in the last yarn over of the previous colour.


LIGHTBULB (starting with yellow, make 2)

R1: 8 hdc in magic ring (8)
R2: [Hdc -inc] x8 (16)
R3: [Hdc, hdc-inc] x8 (24)
R4: Dec, sl st, sc, hdc, dc, 3 dc in same st, dc, hdc, sc, sc, inc in next 4 sts, 6 sc, inc in last 4 sts (34)

Join grey yarn in the second dc from R4 (the first dc in the cluster of 3).
R1: Ch 1, sc in same st. [Sc] x2 (3)
R2-3: Ch 1, turn. [Sc] x3 (3)

Fasten off and weave in ends.

Place pieces wrong sides together and join yellow yarn with a standing sc in any st on the right-hand side.

Single crochet evenly all the way around changing to grey for the grey part of the lightbulb (40)

Fasten off invisibly and weave in ends.

Using a single strand of embroidery floss, sew two lines on the front between R3 and R4, starting from the grey section and ending roughly level with the centre of the lightbulb. Make sure to only sew through the front side of your work.

Find the top centre stitch and using a long piece of yellow yarn, attach keychain to the back of that stitch.
