The 100 Square Blanket

This page contains sponsored links.

This is my 100 square crochet blanket. It is a project that combines creativity, versatility, and a touch of nostalgia, resulting in a beautiful and functional masterpiece. Join me on a journey through the creation of this charming and comforting blanket.

Each of the 100 squares is crocheted in 6 rounds, and there are two different colours in each square. I joined my squares for my 100 square blanket using the join-as-you-go method and, therefore, this meant that from square 2 onwards the sixth and final round incorporated the join-as-you-go method of attaching the squares and building the blanket in rows.

Materials

For this blanket I used Stylecraft Special DK which is a 100% premium acrylic yarn. It’s lovely to work with, comes in 100g balls and the finished blankets are warm, soft, durable and machine washable. Alternatively you can use any double knit yarn you choose.

I chose 10 different colours of Stylecraft Special DK yarn: Parchment, Mushroom, Grey, Pale Rose, Duck Egg, Fuchsia Purple, Raspberry, Mustard, Grape and Storm Blue. I needed 1x100g ball of each. You can purchase this yarn here.

I used a 4mm hook. Each square should measure approximately 9.5cm x 9.5cm. If your square is not measuring near this then you may want to adjust your hook size. Gauge is not critical for this project, but it may affect the yarn quantities needed.

You will also need scissors and a darning needle to sew in the ends. You may also find stitch markers helpful.

Size

A completed six round square should measure approximately 9.5cm by 9.5cm.

The finished blanket measures approximately 102 cm x 102 cm including the 7 round border.

Notes on the Pattern

Each square is crocheted in six rounds; the sixth round is worked using the join-as-you-go technique. Alternatively you can make each square separately and then sew or crochet the squares together at the end.

There are 100 squares in total, arranged in a 10 x 10 format.

Once all 100 squares have been made and joined, a border is worked in seven rounds (using seven different colours) to complete the blanket.

Complete all six rounds to make square 1. You will then work across each horizontal strip adding the next square by joining whilst working the sixth round.

The colour chart for each square is below:

Joining the squares

I joined my squares using the join-as-you-go method where each square is joined to the adjacent whilst working the sixth round. Alternatively you can make each square separately and then sew or crochet the squares together at the end.

I have a tutorial on the join-as-you-go method here. This method is simply slip stitching into the adjacent square in between the clusters on the final round of each square. The tutorial shows how to do this with a traditional Granny Square, so just adjust this to working with half treble stitches instead of the trebles described.

The 100 square border

The border is worked in seven rounds, using the following colours :

  1. Parchment
  2. Pale Rose
  3. Raspberry
  4. Duck Egg
  5. Fuchsia Purple
  6. Mushroom
  7. Storm Blue

You will need approximately 25g of each colour. The border is worked alternating a round of linen stitch and and round of htr clusters.

You will be turning the blanket after each round, so make a note whether you should have right side or wrong side facing at the start of each round. Start with the right side facing for round 1.

Border round 1: use colour Parchment. Right side facing. You will be working a round of linen stitch.

  • Join yarn in any corner space.
  • Ch 3 (counts as 1dc and ch1), *[1dc in the space between the htr cluster, ch1] until you reach the corner, [1dc, ch2, 1dc] in the corner ch2 space, ch1*
  • Repeat from *to* twice more
  • [1dc in the space between the htr cluster, ch1] until you reach the corner space where you started the round, [1dc, ch2] in the corner space
  • Join with a sl st to the second chain of the beg-ch worked at the start of the round.
  • Turn.

Border round 2: use colour Pale Rose. Wrong side facing. You will be working a round of half treble clusters, this will mean 2htr in each chain 1 space.

  • Ch2 (counts as 1htr), 1htr in the same corner space
  • *2htr in each of the ch1 spaces along until you reach the corner
  • [2htr, ch2, 2htr] in the corner space*,
  • Repeat from *to* twice more
  • 2htr in each ch1 space along the final side, [2htr, ch2] in the corner space where you started the round,
  • Join with a sl st to the top of the beg-ch2 worked at the start of the round.
  • Turn.

Border round 3: use colour Raspberry Right side facing. You will be working a round of linen stitch. Repeat as for border round 1.

Border round 4: use colour Duck Egg. Wrong side facing. You will be working a round of half treble clusters, this will mean 2htr in each chain 1 space. Repeat as for border round 2.

Border round 5: use colour Fuchsia Purple. Right side facing. You will be working a round of linen stitch. Repeat as for border round 1.

Border round 6: use colour Mushroom. Wrong side facing. You will be working a round of half treble clusters, this will mean 2htr in each chain 1 space. Repeat as for border round 2.

Border round 7: use colour Storm Blue. Right side facing. You will be working a round of linen stitch. Repeat as for border round 1.

Make sure all your ends are woven in.
