About This Mary Wave Baby Blanket Pattern
This pattern creates a sweet Mary Wave baby blanket worked in a simple treble-wave ripple. It uses DK yarn in five complementary colours and includes full row-by-row instructions for the wave repeats and an attractive sparkly edging. The finished blanket measures approximately 53 x 60 cm — ideal for newborns and prams.
Easy-to-follow rows make this a relaxing weekend project and the pattern includes a full colour sequence for a pretty striped finish. Machine-washable yarn is recommended so the blanket is practical for everyday baby use.
Why You'll Love This Mary Wave Baby Blanket Pattern
I absolutely love this pattern because it is simple yet produces a beautifully textured wave that looks far more complicated than it really is. I enjoy mixing colours, and this design gives a lovely rhythm as the stripes form, which is both calming and satisfying to crochet. The choice to add a sparkly Mint accent yarn gives the blanket a special, playful finish that feels gift-ready. I also appreciate that the pattern is flexible — you can easily change the colour order or add blocks to make it larger without altering the wave structure.
Switch Things Up
I love how easy it is to customize this pattern by changing the colour order to suit any nursery or gift recipient.
You can make the blanket wider by adding extra blocks of 12 chains to the starting chain; this keeps the wave repeat intact while creating a larger throw.
To create a smaller, portable version for a pram, use a lighter DK yarn or a smaller hook to reduce the overall dimensions.
If you want a chunkier look, swap to a bulkier yarn and larger hook — the texture will be more pronounced and the blanket squishier.
I often change the sparkle accent yarn to a different metallic or bouclé to give a different finish and subtle texture contrast.
Try an ombre sequence by using shades that progress from light to dark for a modern, gradient effect across the stripes.
I sometimes add a simple corner tassel or two for a playful finish, but keep them small for baby safety and practicality.
For a more refined look, work a tidy single crochet border instead of the patterned dc edging, and consider blocking lightly to even out waves.
If you like stitch variation, you could substitute the tr2tog decreases with alternative textured decreases, but keep the stitch counts consistent across each wave.
I recommend trying a small swatch of any new yarns and colours together before committing, so you can see how stripes and sparkle look together in real life.
Mixing brands is fine — just be mindful of fibre content and washability, especially for baby items; I always choose machine-washable yarns for easy care.
Common Mistakes & How to Fix Them
✗ Not checking your gauge before starting will change the finished size and drape; make a 10cm x 10cm swatch in treble crochet and adjust hook size to match the gauge.
✗ Forgetting to count chain multiples when starting can make the blanket uneven across the width; ensure your starting chain is a multiple of 12 plus the turning chains for seven wave blocks or more as required.
✗ Pulling stitches too tightly when making the initial chain can make the first row difficult to work into; use a slightly larger hook for the foundation chain if needed to maintain even tension.
✗ Changing colours without securing ends can lead to loose or messy edges; weave in ends as you go or carry yarn neatly along the side to keep edges tidy and reduce finishing work.
