Cozy Corner to Corner Afghan Free Crochet Pattern

I received a few skeins of this gorgeous, soft bulky weight variegated yarn back at Christmas (thanks Elizabeth & Shane!😊) and immediately knew I had to crochet an afghan with it.

I decided to go with a corner-to-corner blanket to really showcase the striping effect of the variegated yarn and I absolutely love the end result. The uneven red and blue streaks remind me of the brush strokes on a painting, blending together in a beautiful way.

Using 4 skeins of yarn and a size 6 mm crochet hook, I was able to make a 47″ x 47″ square afghan. While this pattern is ideal for a small throw/lapghan, toddler blanket, or large baby blanket, it can easily be adjusted to make a larger or smaller size.

Skill Level:

Easy

Materials:
Gauge:

Each block (diagonal box stitch) measures approximately 1” x 1” using a size 6.0mm (J-10) crochet hook and bulky weight yarn

Size of Completed Project:

Approximately 47” x 47” (with border)
Approximately 33” x 33” (without border)

Abbreviations and Stitches Used:

Beg – beginning
Ch – chain
Dc – double crochet
FO – fasten off
Rep or * * – repeat
Sc – single crochet
Sl st – slip stitch
St(s) – stitch(es)
Sp – space
YO – yarn over

Special Notes:
  • Terminology in U.S. terms.
  • Diagonal box stitch (Corner-to-Corner Method) brief description: Beginning with the bottom right corner and working diagonally, increase each row by one block until the desired width is reached. Then, decrease each row by one block until you reach a square shape. See sample images included in the pattern below for clarification.
  • Every other round of the border is comprised of groups of 3 dc sts to mimic the shape of the diagonal box stitch.
  • Round 14 of the border finishes off the afghan with simple shell sts.
  • The yarn shown in the photo tutorial is NOT the same as the yarn used to create the afghan. The variegated yarn used in the afghan blends together really well, which makes it difficult to distinguish stitches clearly. A yarn of different weight was chosen for the sample images in order to help show stitch placement for tutorial purposes.

Note: Treat the sets of 2 dc sts found on each side of the corners as a set of 3 dc. In other words, sc in between the set of 2 dc and set of 3 dc on the sides of each corner.

4 – 13. Repeat Rounds 2-3 five more times. The final round (Round 13) should be a repeat of Round 3.

14. Sl st over to the first ch-2 sp. Ch 1. Sc in same sp. Place 5 dc in next ch-2 sp. *Sc in next ch-2 sp. 5 dc in next ch-2 sp. Sc in next ch-2 sp.* Repeat from * to * until you reach the corner ch-2 sp. Place 7 dc in corner ch-2 sp.

Repeat this process around the entire blanket, alternating sc sts with 5 dc shell sts. Be sure to always place 7 dc in the corner spaces. After the final 5 dc shell st, sl st to the first sc st. FO. Weave in all ends.

*Note: If you decided to add more rows to your afghan to make it larger or altered the stitch count in any way, you may find you have an uneven number of ch-2 spaces to work your alternating (sc, shell, sc) sts into.

In other words, you may end up with a shell st in the ch-2 sp before a corner rather than a sc st. If this happens, I recommend placing a sc into that sp instead of another shell.

If you look closely, you can see an example of this in the β€œBorder – Final Round” image above.

Each side contains the following:
[corner shell, sc, shell, sc, shell,
sc, sc, corner shell]

You can see that the two sc sts side-by-side aren’t very noticeable and do not affect the overall shape of the border.

I hope you’ve enjoyed this pattern!
