Rainforest Crochet Patchwork Squares Blanket

I have wanted to make a crochet patchwork quilt style blanket with solid colour squares for a long time, but did not want to use Granny Squares or traditional corner-to-corner squares. Instead I wanted something that looked modern. After a play around making several swatches and samples I came up with these Crochet Patchwork Squares, which are very simply joined to each other. I loved the way that each square was joined to the next as I went along, and the corners and sides worked out wonderfully straight – so straight that I decided not to have a border, which meant that it retained its modern and contemporary look.

Instructions

This blanket is worked in vertical strips. You start with making the first strip and then you add subsequent strips whilst joining to the previous strip as you go along. Each vertical strip is worked in 12 colour blocks, each made up of 14 rows. The blanket is worked in Half Treble Crochet (htr in UK terms, or hdc in US terms), and is worked in groups of two half treble stitches (htr clusters).

Notes on joining (do a practice sample first)

Once you have made the first vertical strip, you will be then be adding subsequent strips using a slip stitch join-as-you-go. I recommend that you try out this joining method in advance of starting the whole blanket. Do this by making two squares in the first vertical strip and then practice joining the next vertical strip using the slip stitch join-as-you-go described below in Fig. 7 to Fig. 32.

Materials

This section has affiliate links (if you purchase products via my link I receive a small commission, but there is no extra cost to you, this helps me to run my website and provide my patterns and projects free of charge).

For my sample blanket I used Stylecraft Special DK 100% Acrylic yarn in nine colours, using 100g/295m of each colour. This blanket would work brilliantly as a stash-buster to use up your leftovers. You can purchase this yarn here.

I named this project the Rainforest Crochet Patchwork Squares Blanket owing to the colours that I used.

Crochet Hook:  4mm or size needed to achieve gauge 
Yarn:DK weight yarn in nine colours, 100g/295m of each.
The sample uses Stylecraft Special DK in:
Cypress (A) – (100g/295m), 
Parchment (B) – (100g/295m)  
Grape (C) – (100g/295m), 
Meadow (D) – (100g/295m), 
Pale Rose (E) – (100g/295m), 
Graphite (F) – (100g/295m),
Pistachio (G) – (100g/295m),
Fuschia Purple (H) – (100g/295m),
Lincoln (I) – (100g/295m), 
You can purchase this yarn here.
Notions:Scissors
Needle to weave in ends 
Finished size:Approximately 120cm x 120cm, the actual size of your blanket will depend on your tension (how tightly you crochet). Please note that once all of the squares have been worked, the nature of the stitch and the drape of the stitch means that, whilst the first square measured 10cm x 10cm, each individual square becomes slightly longer and narrower. The actual size of my finished worked sample was 119cm x 122cm.
 Skill Level: Suitable for beginners 
Gauge:1 square as per pattern for the first square (14 rows with a starting chain of 17) = 10cm x 10cm (4in x 4in), adjust hook size as necessary  Gauge is not critical for this project, but may affect yarn quantities. See notes above relating to finished size.
