How to Use the Polka Dots Crochet Edging on Another Blanket

Of course, you could use this polka dots edging pattern on any blanket of yours. In order to do so, you need each side of your blanket to have a multiple of 10 stitches (including corner st) for your starting round. You can then simply follow the instructions starting with round 2 in the Waffle Stitch Border section below.

The width of the border is 16 cm / 6.25”.


This pattern uses US notations.

  • st = stitch
  • ch = chain
  • dc = double crochet


Work instructions between [] the indicated number of times or until the end of the row/round. Instructions between () are worked in the same stitch/space.

The final number of stitches is indicated at the end of the row/round between < >.

The turning ch 1, ch 2 don’t count as stitches throughout the pattern except if mentioned.

The pattern is written in crochet shorthand.  For example:

  • “dc 1” means to double crochet in the next stitch,
  • “dc 2” means to double crochet in each of the next 2 stitches,
  • and “2 dc” means to double crochet twice in the next st.

Special Stitches

  • Bobble stitch (5 dc cluster) = [yo, insert hook in indicated st, yo and pull up a loop. Yo, pull through two loops] 5 times in the same space, yo and pull through all 6 loops.

If you’re not familiar with the bobble stitch, refer to my step by step stitch tutorial. It even includes a video on how to do the bobble stitch in a contrasting color.

Tips and Tricks

  • To change yarn color, work last st of old color to last yarn over. Yarn over with new color and draw through all loops on hook to complete st.
  • When using more than one color in a row, working over the unused color in tapestry style.
