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.

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.

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.

sl st- slip stitch

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.



Work 2 sc in each of the two corner stitches



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.

Thank you for such an easy but effective pattern!! I’ve now made 10 of these to donate to my local children’s hospital as I can sit in front of the tv in an evening and work these up quite quickly!

having a slightly uneven edge to a crocheted strip would a Tunisian crochet pick up row solve the problem? This would be used as the basis for a border.

I want to use a different brand of yarn. What ply is the blanket yarn you used? Having been crocheting for 72 years , I know that will work.

I am looking for a blanket pattern that only needs 1060 yards for a 48" X 56" size or so. I was wondering if I can use a Baby blanket pattern, make it wider and higher and use the total # of yards from the pattern and figure it times 2 or 3 to make the blanket bigger? Does that make any sense?

You can divide the surface area of your blanket by the surface area of my blanket and use that to calculate the total yardage. I hope that makes sense.
