Week 2 of The 50 Stitches CAL – The Bobble/Puff Stitch

Welcome to week 2 of The 50 Stitches crochet-a-long!

This week we’re doing the bobble stitch, also known as the puff stitch. I’ve chosen to do this as a colour work square to really show off those bobbles in all their glory.

The bobble stitch is a great stitch to use to add designs to your work, and is commonly used to add writing onto the piece by laying out the bobbles in a carefully arranged pattern.

For this square we’re using a 3.5mm hook and you will need around 70 meters of yarn.

UK translation

single crochet (sc) = double crochet

double crochet (dc) = treble crochet

The Pattern

The bobble stitch needs all the bobbles to be formed on the same side, so alternates with rows of single crochet.

Start with a foundation row of 31 stitches. Your turning chain will count as a single crochet.

Row 1. Single crochet in the 3rd chain from your hook (this will be the 29th chain of your foundation row). Single crochet across the entire chain. This will give you 30 sc in total.


Row 2. Chain 1 and make a double crochet alternate turning chain. Double crochet in the next 2 stitches, join your 2nd colour (do this by not completing the 2nd dc, leave last 2 loops on your hook then finish the stitch by pulling through the new colour)

Make your first bobble in the next stitch. Remember to always carry the colour you’re not using at the front of your work so it won’t be seen in the finished square. You need to keep the carried yarn taught.

The bobble is made by dc5tog (double crochet 5 together) to see how to do this To do this start making a double crochet, but leave the last 2 loops on your hook. Then in the same stitch start another dc, but leave 3 loops on your hook. Carry on doing this until you have 5 half completed double crochet and 6 loops on your hook. Yarn over and pull through all loops then rejoin your first colour and chain 1. then rejoin your first colour and chain 1.

*Double crochet in the next 5 stitches. Bobble* continue this pattern until you have 5 bobbles. Finish the row with 2 dc. You can cut off the colour you’re using for your bobbles. You will have 5 bobbles and 25 double crochet in the row


Row 3. Chain 1 and make an alternate single crochet turning chain, and single crochet across the entire row, taking care not to make a stitch in the chain before the bobble where you changed colour.


In this row we’re going to offset our bobbles

Row 4. Chain 1 and make an alternate double crochet turning chain, then dc in the next 5 stitches. Bobble. *5dc, bobble* continue this pattern across until you have 4 bobbles in total and finish the row with a dc in the last 5 sc. You will have 4 bobbles and 26 double crochet in the row.


Row 5. Alternate sc turning chain, single crochet across the row

Repeat rows 2-5 until you have 19 rows in total. You should finish with a row of single crochet.

For the border

Single crochet in each stitch across the top and bottom, adding an extra stitch for each corner.

Down the sides make a sc in the side of each sc, and 2 sc in the side of each dc – except in row 1 and row 19. In the side of the single crochet in these rows make 2 sc. This will make your stitch count as 32 stitches across each side and 124 stitches total (remember the extra stitch corner stitch is counted in the stitch count for both sides)

I recommend blocking your square now.

Joining with the first square

If you are joining as you go, we need to add the interlocking border and weave it into the border of the seed stitch square so they are joined together. Use a 4mm hook for this part of the border on all squares.

Start the border in the extra corner stitch on the bottom left hand side with a standing single crochet, and single crochet in the next corner stitch.

*Chain 4, skip the next 3 stitches, single crochet in the next two stitches* repeat this pattern across the bottom edge until you reach the next corner (you should have 6 loops). Make a single crochet in all 3 corner stitches. Carry on the pattern above. Do this for 3 sides.

When you get to the top left corner, single crochet in the 3 corner stitches then chain 4. Pull up a loop, then insert your hook into the top right loop of the seed stitch square. Hook the loop from your chain 4 and pull it up through the seed stitch loop. Pull your loop tight, skip 3 and single crochet in the next 2 stitches of the bobble stitch square.

You should have joined the first 2 loops together. Repeat this for all 6 loops until you get back to the bottom left hand corner. Single crochet in the corner stitch, and join into the standing stitch.

You can now tie off and weave in your ends.
