Easy Crochet Baby Blanket Pattern (Shell Bay)

With only a 2-row pattern repeat, my free crochet baby blanket pattern is an easy project suitable for confident beginners.

If you’re not such a fan of sewing like me, you’ll be pleased to know that even though the pattern works with two colours on alternating rows, there is minimal sewing in of ends!

This crochet pattern is written in US and UK terminology.

The shell pattern crochet baby blanket looks more difficult than it is!  Basic crochet stitches are used – UK double crochet / US single crochet and UK treble crochet / US double crochet.

I’ve added a simple border. This baby blanket didn’t need anything more elaborate!

Design Inspiration

I started to use the two-colour scale stitch in a pattern for a shawl but the Aran cotton I was using made it very heavy so it wasn’t suitable.

I loved the way the contrasting colours looked and knew I had enough DK in my stash to use the pattern in a baby blanket.  And a bonus, using acrylic makes this a lightweight blanket, suitable for babies!

The blanket’s name is inspired by the fan shape of the stitches which look like scallop shells.

One of my local beaches, Shell Bay, is named after the shells that were once common along this stretch of Studland. 

The turquoise reminded me of the sea.

And so I named this baby blanket the ‘Shell Bay’ blanket.

How the blanket pattern is worked

Multiples of 6 stitches plus 1 (add 3 for foundation chain).

I’ve used two colours – a main colour and a contrasting colour, in alternating rows.

The fan shape is created by working 5 double crochets in the single crochet from the previous row and the next row, 5 doubles together.

Double crochet highlighted where the treble 5 stitches will be worked
single crochet from the previous row where the double 5 will be worked
5 treble crochet in the double crochet from the previous row

stitches numbered where the pattern is treble 5 together
Numbered stitches that are worked for the double 5 together

The main colour is used in row one, the foundation row.

The stitch from the end of row one is held on a stitch marker. 

Row two, the pattern returns to the beginning of row one (no turning after row one) where the contrasting colour is joined.  Row 2 is worked in the same direction as row one.

This row ends with a double/single crochet, working the last pull through of this with the loop of the main colour from the stitch holder.

This row is turned at the end. 

Row three is worked using the main colour.  At the end of row three, the stitch is held on a stitch marker.

Rows two and three are then repeated throughout, alternating the main colour and the contrasting colour.

The border is one round of double/single crochet and one round of half treble/half double crochet.
