Colour layout
Overview
The pattern is made in a rainbow sequence with the first and last colours ‘flowing’ into each other. This creates the illusion of random colours, but it definitely has a pattern!
The flow is as follows: Start at the bottom left, follow the first row to the right. Move up a row, and follow that one to the left. Move up a row, follow that one to the right. Etc.
Motifs per colour
You can create all the motifs in advance, and join them all at once. Or join them per row as you go: it’s up to you!
You will need the following number of motifs:
- Motifs: 12 of each for colours A-N
- Top half motifs: 1 of each, except for colour K and L (0 motifs in these colours).
- Bottom half motifs: 1 of each, except for colour M and N (0 motifs in these colours).
Create your own colour sequence
Using the information I’ve given you, you can easily create your own sequence. It doesn’t have to be a rainbow to create this effect, as long as you make sure the first and last colour ‘flow’ slightly into one another. I would recommend using a lot of colours (10+) and drawing it out beforehand.
The reason for drawing it out beforehand is that with fewer colours, you have a higher chance of motifs of the same colour ending up right above each other in separate rows. There’s nothing particularly wrong with that, I just didn’t like it. So that’s why I’m urging you to visualise your own version before you start.
If you want to make your own colour layout, you can use the empty template at the end of the pattern.


Techniques
Full motif
Make a magic loop, and ch4 (photo 1). Make a beg-dc4tog (photos 2-3), ch3 (photo 4). The ch3 spaces are the ‘midsections’ between the triangle’s corners. Make another dc4tog (photos 5-6). Ch4 to create your first corner space. Keep following the pattern and make dc4togs, ch-3 and ch-4 spaces. You will see the corners of your triangle starting to take shape in the ch-4 spaces (photo 7). Join with a ss in the top of your beg-dc4tog (photo 8). You can now pull the magic loop tight.
Start Round 2 by chaining 3 (photo 9). These 3 chains will be skipped when joining at the end of the round - they purely function to fill up empty space between the first and last stitch of the round. Make 1 dc in the same space, this is your first proper stitch of the round (photo 10). 3hdc in the ch-3 space (photo 11). Using a smaller stitch makes the sides of your triangle flatter. Work 1dc in the top of the next dc4tog (photo 12). Create a corner by crocheting 3dc, ch4, 3dc in the ch-4 space. The corner created in the previous round now becomes even more obvious!
Continue following the pattern, and finish the round with a ss in the first dc (so not the ch3!) (photo 13). The triangle shape is now quite pronounced. You can see that the sides of the triangle are straight instead of round, thanks to the hdc.
Round 3 is fairly simple. Ch3, which again purely functions to fill up empty space, and then work 1dc in each stitch of the previous round. In each corner, make (3dc, ch4, 3dc). Join with a ss in the first dc and fasten off (photo 14).







Half motif
Half motifs are very similar to the full motifs, only they are worked in rows instead of rounds. This means that you turn your work to the wrong side in Row 2. To visualise what you’re making, take one of your full motifs and fold it in half. That’s roughly the pattern we’re following.
In this example, a top half motif is crocheted. Bottom half motifs are very similar to the top ones, so I only photographed one version to display the techniques.
Start by making a magic loop. Ch4, that counts as the first dc and chain space (photo 15). Make a dc4tog (photo 16), ch3, another dc4tog, and then ch4 to create the corner space. Work another dc4tog, ch1 and make a final dc (photo 17). Pull the loop tight. As you can see, you do not crochet all the way around the loop, but rather only halfway.
Ch3 and turn your work so you’re facing the Wrong Side of your work (photo 18). The ch3 you’ve made counts as a dc. Make another dc in the ch-sp of the previous row, and another one in the top of the dc4tog (photo 19). Create the corner by making (3dc, ch4, 3dc) in the corner space (photo 20). We’ll now create a triangle side much like for the full motif, by working 1dc in the top of the dc4tog, 3hdc in the ch-3 space, 1dc in the top of the next dc4tog. Finish your row by making 3dc in the chain space, ch1, and then 1dc in the third ch of the four ch’s you started this motif with. That concludes Row 2 (photo 21).
(The reason the ch3 counts as a stitch in these rows, but not in the full motif is because of aesthetics. If it wouldn’t count, I had to make another dc in the same space and that would cause the flat edge of the half motif to ‘bulge’ outward. It simply didn’t look pretty).
Ch4 (which again counts as a first dc and chain space) Make 3dc in the chain space. Crochet 11dc over the long side, and shape the corner by crocheting (3dc, ch4, 3dc) in the corner space. Make 6dc over the short side, and cut your yarn. (photo 22).




Joining
We join our motifs with a flat ss join. This creates a beautiful flat and flexible appearance. It’s quite easy once you get the hang of it!
To start, border your first motif as per the pattern with 1hdc in each stitch, and (3hdc, ch3, 3hdc) in each corner (photo 23). Work up your second motif in a similar way to a joining side, ending with the 3hdc in one corner (photo 24). This will be your first join.
Put the motifs WS together, ch1 and make a ss in the corner space of the opposite square (photo 25). The motifs are now fastened to each other. Make 1hdc in the corner space of your current motif (photo 26). Remove the active loop from your hook, and insert your hook from back to front in the back loop of the first corner-hdc of the other motif (that’s the loop closest to you because you’re holding it WS forward). In photo 27, it’s indicated with the green arrow. Once you’ve inserted your hook through that loop, pick up the loop from your yarn again and pull it through (photos 28-30). This basically makes a ss through the back loop of the other motif.
And that’s all there is to it! Every time you create a stitch on your current motif, you remove your hook from your yarn, go through the back loop of the other motif, pick up your active loop and pull it through. It sounds cumbersome but you’ll get quite handy with it after a few tries. Photos 31-34 show you what the next couple of stitches, and the end result of your join look like. You finish a side with a ss in the chain space. If need be, you ss in the chain space of the next motif you’re joining and continue as before.
This join is used for all motifs, also the half ones. Really all you have to remember is when you join a stitch, you ‘ss’ it to the back loop of the corresponding stitch on the other motif!






Crochet pattern
Motifs
Start with a magic loop.
The ch-4 spaces are the triangle’s corners in the next rounds. The triangle shape starts to form here. Skipping the ch3 at the beginning helps fill up the space between the first and last stitches of the round.
Half motifs
Please note that the top and bottom half motifs are reversed on the right and left sides of the blanket. So what’s a top half motif on the left side, is a bottom half motif and vice versa. Check the colour layout to see how many you need to make of each in each colour.
Top half motifs
Make a magic loop.
Bottom half motif
Make a magic loop.
Joining
I joined the full motifs together first. After those were done, I squared off the blanket with all half motifs on the long sides. All joins are worked on the RS of the blanket.
Second and next rows of motifs
This join basically boils down to this: For each stitch that needs to be joined, find the opposite stitch on the other motif and pick up that back loop after you make a stitch on your current motif.
When you start joining your second row and every even row from here, your first motif will be joined in one corner only as there are no other motifs to join the sides to, yet. Follow the instructions for the first motif, but join with a ss in the corner-sp of the opposite motif.
When joining sides to two motifs, make sure to ss in the corner-sps of both adjacent motifs you’re joining to.
It helps to position your triangle in the blanket to visualise which sides you are joining. You alternate joining one or two sides of each triangle. It usually takes a few motifs before you develop a feel for it.
Joining Half motifs
I filled up each gap by joining the top half motif first, and then the bottom half motif.

Border
The first two corner spaces contain 2dc instead of 2hdc. This is to offset some of the (small) height-difference going on in those corners due to the positioning and joining of the motifs. If you find this difficult, simply crochet 2hdc. It won’t show up noticeably in the final border.
You’re making 2hdc on one side of the corner, and 1hdc on the other side. The reason for this is that when you work in Rounds, the slanting of stitches causes the corners to look slightly crooked. By working 2hdc we’re offsetting this slant and making perfectly square corners. Trust me, it works!
Cut yarn, weave in all ends. Block the blanket to size.

Adjusting the size
You can adjust the size of the blanket by adding more motifs. I recommend adding (or removing) in multiples of two: add two motifs to each row (i.e., 16 motifs per row) or add two rows to the blanket (i.e., 14 rows). This way, you will not have to adjust any instructions for the edge other than working more or fewer repeats from the pattern as written.
Two motifs add ~13 cm (5 in) to the total width of the blanket, and two rows add ~24 cm (9.5 in) to the height of the blanket.
