Crochet Granny Stripe, Mock Granny Stitch Blanket

Share the Love!

Have you always loved the classic look of crochet granny stripe blankets? I have tried to imitate the look of a crochet granny stitch with Bernat Blanket yarn in this crochet blanket. I hope you like the outcome.


Crochet Granny Stripe Blanket


Crochet Granny Stripe Afghan


The regular crochet granny stripe pattern left big holes when working with this yarn. So I modified it to use half double crochet stitches and reduce the gaps to make a no holes baby blanket.


Blue Crochet Granny Stripe Blanket


I used shades of blue to make a baby boy blanket, but can you imagine the endless color combinations that are possible with this crochet afghan? I cannot wait to try it in some girl colors.





This is a super quick project and it worked up in 6 hours. There is no fastening off after each color change, just dropping and picking up the yarn later. I love an easy project that looks great, do you?

1. Super Bulky yarn in 3 colors. I used Bernat Blanket in color Light Teal and Bernat Blanket Baby in colors Vanilla and Seafoam.

2. An N/P (10mm) crochet hook.

3. Yarn needle with a big eye to weave in the tails. A smaller hook like a K(6.5mm) will also work.

40 inches wide and 41 inches long.



200 yards of the cream and dark blue color and 300 yards of the light blue color. Each skein of Bernat Blanket yarn is 220 yards long.


Stitch Abbreviations

sc-single crochet

hdc- half double crochet

sl st- slip stitch

sk- skip


Crochet Pattern


1. You will change colors every row. To join a new color while working the last hdc of the round, start working the hdc and when you have 3 loops left on your hook, pull through the new color. You can see a video here: How to Join New Color.


2. When you are changing colors, you don’t fasten off. You just drop the previous color to pick it up later. The yarn strands that run along the edge will be concealed when you add the border.


3. To manage your 3 skeins without tangling, whenever you switch colors, bring the new color over the other two skeins to your left, and keep the other 2 skeins to your right.


4. Beginning ch-2 counts as a hdc throughout the pattern.


With the dark blue color and 10mm crochet hook, ch 67. You can chain any multiple of 2 +3  if you want to make your blanket a different width.


Row 1: 1 hdc in 3rd ch from hook, *(sk next ch, 2 hdc in next), repeat from * to last 2 chs, sk next ch, 2 hdc in last ch, join the light blue color while completing your last hdc, ch 2 and turn.——-33 hdc clusters


Row 2: 2 hdc in next st, *(sk the next st, 2 hdc in next), repeat from * to last 2 sts, sk the next st, 1 hdc on top of beg ch-2 while joining the next color cream, ch 2 and turn.——-32 hdc clusters and 2 hdc


Row 3: 1 hdc in the same st as ch 2, *(sk next st, 2 hdc in next), repeat from * to last 3 sts, sk the next st, 1 hdc in next st, 1 hdc on top of beginning ch-2 while joining back the dark blue color, ch 2 and turn.——33 hdc clusters


Row 4: 2 hdc in next st, *(sk next st, 2 hdc in next), repeat from * to last 2 sts, sk next st, 1 hdc in beg ch-2 while joining the light blue color, ch 2 and turn.——–32 hdc clusters and 2 hdc


Keep repeating Rows 3 and 4 until you have 43 rows keeping your color sequence in the following order:

dark blue, light blue, cream, dark blue and so on. Your 43rd row will be dark blue. Fasten off.


Crochet Blanket Border

Unravel the last hdc and join light blue while completing it.


Note: Take care to pack your sc sts close enough to conceal the yarn strands carried along the side, but not so tightly packed that your blanket edge starts waving.


Round 1: Ch 1 at the corner, 2 sc in the point right after the corner, evenly distribute sc sts along the row ends. When you reach the next corner, work 2 sc into each st on either side of the corner, work 1 sc across the free loops of the foundation ch until you reach the next corner.



Continue to work sc sts all around your blanket working 2 sc into each st on either side of the corner (See pic above). When you reach back where you started and have only 1 st left, 2 sc in the last st, sl st to first sc. Do not turn.


Note: In the next round, if your corner looks tight, feel free to add more increases near the corner without skipping any sts between them.


Round 2: Ch 1, 2 sc in next st, [*(sk the next st, 2 sc in next), repeat from * until you have 1 st left for the next corner, 2 sc in each of the next 3 sts to turn the corner].


Repeat the part between the [ ] to work the border all around your blanket, when you reach back where you started and have 2 sts left, work 2 sc into each of these sts, sl st to the first sc. Fasten off.


Finishing the Crochet Granny Stripe  Blanket

Weave in any tails left.

    I am on the third row and it only measures 31” wide. Do I need to start over, add more chains to make it wider ?

      Yes, you might have to.

    I’m having some issues with making this blanket. I seem to always have the incorrect number of stitches at the end of each row. For example, when it says 3 stitches at the end I often have only two and when it says 2 stitches at the end of your row I have 3. What am I doing wrong? I’ve retried so many times and it always ends up like that.

      Yes, why not? It is your choice.

    To change sizes you said 2 +3, does this mean multiples of two and then add 3 more to your final width? 2+2+2+2etc+3?

    • Shehnaaz

      Yes, you are right.
