Can beginners crochet granny square blankets?

Absolutely! This granny square blanket pattern is a classic that’s known for being very beginner friendly. By the way, it’s super quick to crochet as well, since you will be using bulky yarn.

Additionally, you will use only three shades of yarn, so not too many ends to weave in. You will not only love how fast it is to make, but how beautiful the end result is.

Before you go to the pattern, let’s dive into some useful information.

Classic Granny Square Throw Blanket

How long does it take to crochet a granny square blanket?

It will take you approximately 7-8 hours to crochet a throw blanket with a classic granny square. Of course, that is the total time, it may take you weeks depending on how many hours a day you work on it.

It really is that quick! That was how long it took me to crochet the blanket shown here, including joining the squares and making the border.

Certainly, everyone has their own speed and it will depend on other factors as well, such as the size of the blanket you will make, and the yarn thickness.

What’s the best yarn for a crochet granny square blanket?

Bulky yarns are the best for large blankets because they build up super quickly. By the way, I used Hue + Me, a yarn by LionBrand, which is a super soft wool blend with a dreamy palette.

Hue and Me comes in 18 shades and you can mix any of them together that the combo will be simply gorgeous. I love the super cozy farm house feeling we can get from those shades.

But you can use any yarn you like, as granny squares are forgiving and easy to adjust to any size.

Does the fiber content matter?

Not necessarily! Wool blends create soft and cuddly blankets, but there are great quality acrylic yarns that will work just fine as well.

The fiber content of Hue + Me is 80% Acrylic | 20% Wool and it is a bulky (5) weight yarn. This yarn is so squishy and cuddly.

I am excited to have a new blanket to cuddle with when I am sitting in my couch now. Or to simply use it as a decor piece.

Only 3 shades of yarn for this granny square blanket

The amount of yarn for a granny square blanket?

You will need approximately 49 oz of bulky yarn to crochet a throw blanket. That is a total of 13 skeins of 4.4 oz Hue & Me yarn. Obviously, if you are using a different yarn brand and/or thickness, that amount will vary.

Also, there is the factor edging size. If you are making a wider edging, you will obviously need more yarn. For the blanket pictured here, you will need this amount and colors of Hue and Me:

  • Ozone (C1): 13.8 oz | 391 g, 430 yds | 393 m, or 4 skeins (you will use some of the 4th skein).
  • Peacoat (C2): 14.52 oz | 412 g, 452 yds | 413 m, or 4 skeins (you will use some of the 4th skein)
  • Arrowwood (C3): 20.40 oz | 578 g, 635 yds | 580 m, 5 skeins (you will use some of the 5th skein)

Pattern notes and instructions

  • Ch 3 in the beginning of rounds counts as a dc.
  • This granny square blanket was made using the classic technique. The classic granny square is built with chain 1 spaces, clusters and ch 2 spaces in the corners. 
  • A cluster consists of a group of three double crochet stitches. So, the math concept in a classic granny square round is very simple: a cluster for every ch 1 space, a ch 1 space for every cluster, corners with (1 cluster + chain 2 + 1 cluster).
  • Making two double crochets in the corners is what creates the increases. Having said that, every round will have 4 extra clusters each.

Square size:

Gauge is not important for this granny square blanket crochet pattern. A granny square will measure approximately 8”x 8” (20 x 20 cm), if you use the same yarn weight and hook size.

You may add rounds to each square, as needed, to achieve other sizes if you like.

How to customize the size of the blanket

Let’s imagine a granny square in this pattern is two big for a lovey blanket, for example, you can do less rounds per granny square. Or, you can use a smaller yarn to reach the size closest to what you are looking for.

The sizes above are some of the most popular sizes. However, edging is not included as it varies depending on personal preference.

A classic granny square size can be anywhere between 8” x 8” (20 x 20 cm) to 12” x 12” (30 x 30 cm). Butt of course, you can make the squares as small or as large as you want.

Yarn color instructions

  • Make 21 squares with C1 (round 1-3)
  • Make 21 squares with C2 (round 1-3)
  • Then use C3 to finish all the squares (round 4)
  • Join the squares with C3

Assembling the granny square blanket

This granny square blanket crochet pattern width will have 6 squares and the length will use 7 squares. Sewing instructions are in the “join the squares” section below. Join the squares alternating the colors.

When it’s time to join them, follow this chart to set up the layout and for the sewing guide.

How to join granny squares with the Mattress Stitch

  1. To start, grab the first 2 squares and align them against each other, wrong sides facing each other.
  2. Follow the color layout in the chart above, in the “how to arrange the layout” section, to assemble the blanket. 
  3. Thread the tapestry needle with a strand of yarn C3, or a contrasting color, about 24” longer than the width of the blanket. Here, the yarn color you will use to join the squares is your choice. So, use the one you think will fit your blanket better.
  4. Start mattress stitching, from right to left. Or left to right, if you are left-handed.
  5. With this sewing method, you will work through the back loop only of the stitches in last round of the granny squares. I chose this method because I am using bulky yarn, it makes the seam less heavy, not so bulky.
  6. Start with the corners. Each corner has two chains, start with the one immediately before the row you will sew. 
  7. First, insert the needle and draw the yarn through the loops, pulling the strand all the way through.
  8. Leave a tail to make a knot and secure it later. This and all the other tails can be weaved in later after you complete the joining process.
  9. Continue this process of inserting the needle in both loops at once, one stitch at a time. Make sure you pull the strand all the way through. 
  10. When you get to the next corner of the two granny squares, grab two more granny squares and continue stitching.
  11. Join as many squares as needed to achieve the width of this crochet granny square blanket. For this specific pattern, you will have 6 squares.
  12. Fasten off and cut the yarn at the end of each row. You can weave in the end now or do it later.
  13. At this point, you have two rows of squares. Once you stitch the two last squares, go back to the right side (or left, if you are left-handed) and start a new row. Follow the same steps over and over until you complete all rows.
  14. Once you’re done with the horizontal sewing, start sewing it vertically. See the chart above on how to set up the layout.

    A granny square blanket crochet tutorial

    There are several ways to join granny squares. You can even join them as you go. In fact, if you look up online, you will find many tutorials. Feel free to use the one you feel most comfortable with. I used this hand sewing method with the whip stitch. 

    I am using a contrasting color of yarn to join for the purpose of this tutorial. But I chose to use the same color I used to crochet the last rounds of the granny squares to join my finished blanket.

    Basically, you will whip stitch through the back loop only of the stitches in last round of the granny squares.

    See “how to join the granny squares” section above for a detailed step by step.

  6. Crochet the edging with sc sts

    Rnd1: Attach yarn C2 to any stitch in the border, sc around the entire blanket, work (1 sc, 1 ch, 1c) into each of the four corners of the blanket. FO. Cut the yarn
