This knit brick and mortar baby blanket is one of those patterns that looks impressive but works up surprisingly easily once you get the rhythm. The textured “bricks and mortar” effect is created by alternating colour blocks with a white offset border — the colour blocks form the bricks, and the white forms the mortar. It’s a beginner-friendly knit baby blanket with serious wow-factor, perfect for baby showers, gender-neutral gifting, or treating a new little one in your life.

The knit brick and mortar baby blanket uses simple slip stitch colour work — no intarsia, no fair isle, no fancy techniques. If you can knit, purl, and slip a stitch, you can make this.

Pattern Notes

In this knit brick and mortar baby blanket, the colour blocks form the bricks and the white offset creates the mortar between them. You can use whatever colours you love — I went neutral for a gender-unknown baby shower, but this pattern is gorgeous in any palette:

• For a baby boy: blue ombre (light blue, sky blue, navy, denim, slate)
• For a baby girl: pink ombre (blush, dusty rose, mauve, coral, magenta)
• Gender-neutral: warm neutrals (cream, oatmeal, sage, dusty mint, taupe)
• Bold & modern: jewel tones (emerald, mustard, terracotta, plum, navy)

Don’t stick to my colour choices — pick what makes you happy. This knit baby blanket pattern is your canvas.

Materials

• Main Colour (MC): 1 ball of baby yarn in white (this is the border and the mortar between the bricks)
• Contrast Colours (C1-C5): 1 ball of each contrast colour — I used 5 different colours from the Red Heart Baby Hugs Light line
• Size 6 (4.0mm) circular needle — or the suggested needle size to match your baby yarn
• Tapestry needle for weaving in ends
• Scissors

Tips for Knitting a Brick and Mortar Baby Blanket

Use Stitch Markers Generously

Place a marker every 10-15 stitches across your row. It makes tracking the slip stitch pattern much easier, especially when you’re learning the rhythm.

Don’t Pull the Slipped Stitches Too Tight

The mortar between bricks should sit relaxed against the blanket. If you pull the white slip stitches too tight, the blanket will pucker. Loose and easy is the goal.

Block Your Finished Blanket

Blocking opens up the stitch pattern and helps the blanket lay flat. For a baby blanket, wet block by soaking in cool water, gently squeezing out excess, then pinning to shape on a clean towel and letting air dry fully.

Plan Your Colour Rotation

I rotated through C1-C5 in order, then started over. You can repeat the same colour back-to-back for thicker bands, alternate every other row, or do an ombre fade. The knit brick and mortar baby blanket pattern is forgiving — experiment!

Frequently Asked Questions

Is the knit brick and mortar baby blanket suitable for beginners? Yes — if you know basic knit and purl stitches and can slip a stitch, you can make this. The slip stitch colour work technique is much easier than it looks.

How much yarn do I need? One ball of white baby yarn for the main colour, plus one ball each of 5 contrast colours. Total: 6 balls of baby yarn for a standard-size baby blanket (approximately 32″ x 32″).

Can I make this larger? Absolutely. To make it bigger, cast on more stitches in multiples of 6, plus 5 for the border (so 149, 155, 161, etc.). You’ll need more yarn proportionally.

What if I only have 3 contrast colours? No problem — just rotate through your 3 colours in a repeating sequence. The pattern still looks beautiful.

Is there a PDF version? Not yet — but you can bookmark this page or print it directly from your browser. If you’d like me to make a PDF version available, drop me a note in the comments!

What yarn weight should I use? Baby yarn (DK/sport weight, #3) works best for soft drape and is gentle on baby skin. Heavier yarns will work but the blanket will be denser.
