  • DK Weight Cotton Yarn in 4 different colours
    (I used Paintbox Yarns Cotton DK in Sky Blue, Lime Green, Buttercup Yellow and Pillar Red)
  • 3mm crochet hook
  • Yarn needle, scissors


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


The pattern is written using US terminology and measures approximately 3.5″ x 4.5″ (9cm x 11cm) when using the materials listed.

The ch 2 at the beginning of each round does NOT count as a stitch. Pull the chains tight for a neater bottom edge.

The border round is worked with the wrong side facing you.

Colour changes take place in the last stitch of the round as described below:


Yarn over and insert your hook into the last stitch. Yarn over and pull up a loop, 3 loops on hook. Drop your working yarn and pick up the new colour. Draw the new colour through all 3 loops on your hook to finish the stitch.

Tip: Crochet over your ends where possible.
