DIY crochet baby blanket

Crochet Baby Blanket

There aren’t many things that are cuter than a baby, but we reckon this cosy, star-emblazoned baby blanket comes a close second. Mandy O’Sullivan’s crochet baby blanket is worked in the softest chenille-style yarn and it’ll keep your little ‘un as snug as a bug in a rug, and look adorable doing it, too. Plus it’s adorned with matching pom poms that finish the whole thing off beautifully.

If you’ve never tried corner-to-corner (C2C) crochet, you’re in for a treat. Using a series of small squares to create a pattern, you’ll begin at one corner, then work towards the opposite corner, following the chart to build a grid of tiles in different yarn shades.

As C2C crochet uses basic techniques, the style is easy enough to learn. It might help to mark off each diagonal row on the chart as you go through, and to practise the C2C stitch before you dive into the design itself.

This blanket uses the C2C stitch pattern, starting at one corner and working diagonally in treble blocks to the opposite corner. Follow the colour scheme in the chart, reading diagonally from the bottom right to the top left. Each square represents one block of 4tr.

Change colour on the last pull through of the last st in the previous colour. Drop the previous colour and pick it up when needed again (usually the next row). If the colour doesn’t fall in the correct spot, ss through stitches to work the yarn into position. Tension isn’t important – just keep the blocks even so they align. 

Working C2C

Row 13 continue to make blocks using Yarn A until you reach the 5th block of this row. This block is where the colour changes to Yarn B to make the bottom right leg of the star pattern.

Change to Yarn B on the last part of the last tr in block five and drop Yarn A (do not cut). Using Yarn B, ss into top of next 3ch, ch3, 3tr in the same 3ch-sp. Change to Yarn A and drop Yarn B. You will now have three balls of yarn attached – two balls of Yarn A either side of Yarn B. Continue to finish the row as normal with the new ball of Yarn A.

Rows 14-37 continue to work the rows, changing colours where indicated on the chart, starting to decrease at Row 23 on lower left corner and at Row 29 on the top right corner.

Note: on Rows 33 and 34 you will need three sections of Yarn A and two of Yarn B, on these you can just ss across the back of the work to move your yarn into the correct position.

Rows 38-51 continue to decrease with Yarn A until row 51.

Finish with a ss, cut yarn and fasten off. Weave in all remaining ends.


To make a pom pom, wrap Yarn B around your hand 20-30 times. Slip the loop off your hand, then secure around the middle with a length of Yarn C. Cut the loops, trim to neaten, then use the Yarn C to tie it to the corner of the blanket. Repeat for the remaining three corners.
