The 100 Square Blanket

This is the 100 Square Blanket. It is a project that combines creativity, versatility, and a touch of nostalgia, resulting in a beautiful and functional masterpiece. Join the 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.

Skills Required

Working in the round.
Using the join-as-you-go method of joining Granny Squares.
Knowledge of basic stitches is assumed.

Materials

Yarn: You will need 100g/295m of each of 10 colours of DK yarn – a total of 2950m. This sample blanket was made with 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.

You will need ten colours of Stylecraft Special DK yarn: Parchment, Mushroom, Grey, Pale Rose, Duck Egg, Fuchsia Purple, Raspberry, Mustard, Grape and Storm Blue. Each 1x100g ball of each.

Hook: 4mm hook or hook size to achieve gauge

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

Gauge

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.

Size

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; for square 1 complete all six rounds, for all subsequent rounds the sixth round is worked whilst joining to the adjacent square 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.

Written Instructions

This is the basic pattern for each square. Make square as per below. For subsequent squares work the sixth round whilst joining to the adjacent square as outlined below in the joining section.

Round 1:

Using yarn A, make a magic ring (or make a slip knot, ch4 and ss into the first ch to form a ring).
Ch 3 (counts as 1tr), 2tr into magic ring, [ch2, 3tr] 3 times into magic ring, ch2.
Close the magic ring.
Ss into the top of the beg-ch3 to close the round
Turn the square over.

Stitch Count: 4 groups of 3tr with 4 ch2 corner spaces

Round 2:

Ss back into the corner space. Ch 3 (counts as 1dc and ch1), *sk st, 1dc in the next (this will be the centre st of the treble cluster from the round below), ch1, sk st, (1dc, ch2, 1dc) in the corner ch2 sp, ch1*

Joining the squares

The squares and joined 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 involves 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 Blanket border

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

Parchment
Pale Rose
Raspberry
Duck Egg
Fuchsia Purple
Mushroom
Storm Blue

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

Join yarn in any corner sp.
Ch3 (counts as 1dc and ch1), *[1dc in the sp between the htr cluster, ch1] until you reach the corner, (1dc, ch2, 1dc) in the corner ch2 sp, ch1*
Repeat from *to* twice more
[1dc in the sp between the htr cluster, ch1] until you reach the corner sp where you started the round, (1dc, ch2) in the corner sp
Join with a ss to the second ch of the beg-ch worked at the start of the round.
Turn the work over.

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 sp

2htr in each ch1 sp along the final side, (2htr, ch2) in the corner sp where you started the round,
Join with a ss to the top of the beg-ch2 worked at the start of the round.
Turn the work over.

Border round 3: use colour Raspberry Right side facing. You will be working a round of linen/moss 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 ch1 space. Repeat as for border round 2.
