Geometric shapes and designs are my absolute favourite! I designed this Geometric Square Crochet Blanket so that it features different shapes. The blanket features four designs: triangles, hexagons, squares and rhombuses. Each design features a combination of the single crochet stitch and one of the following stitches: the puff, bobble, treble and berry stitches! Using these stitches gives the blanket a similar ‘bobbly’ texture which helps bring the designs together.
The pattern can be easily adapted as you can use your own colour preferences, pick and choose if you want to use a specific design more than another and you can also adapt the blanket size to fit your needs. You can also change the way that the crochet squares are joined up to give your blanket a different style. So the combinations are endless!
In this blog post, I will walk you through the first crochet blanket square featuring the Triangle Puff square. In subsequent blog posts I will share the other three designs and in a separate blog post I will go over how you can assemble the blanket squares and crochet a border as well as how many squares I needed of each design and the colours I used. Each crochet square measures approximately 8×8 inches. Check out part 2 of this blog series, featuring the Square Berry Square.
Check out the detailed written instructions below and directly below a video tutorial:
For the Triangle puff square you will need:
- 4.00 mm crochet hook
- DK yarn, I used Paintbox simply DK 100% acrylic in Dusty Rose (141) and Peach Orange (154) but you can use any other colour or yarn. If you use a different yarn you might end of up with a differently sized crochet square
- Tapestry needle to weave in your ends
- Pair of scissors

Fasten off your yarn and weave in your ends.

Here is a diagram in case you prefer following a visual pattern:
The empty cells represent single crochet stitches and the ‘x’s are puff stitches. Note that each row finishes with a chain 1. This is a turning chain and does not count towards your stitch count.

Tips for making the puff stitch:
- Each time you pull your hook through the stitch, give this a little tug to make sure no extra yarn has been caught. this will give your final stitch a good look.
- Make sure that when you yarn over, that you keep your tension even but not too tight. This will help you when pulling your hook through all the loops.
Happy Crochet
