Now let’s look at how each one of these parts of a stitch performs after working a few Rnds of stitches. I’m making the tops of these 3 stitches shades of purple and the bottoms of the stitches (the V and back loops) different shades of green. I’ll continue to make the same color changes in the exact same spots in the next round to look at how the stitches change positions and what they look like.

Step 1: Yarn over and insert hook into the stitch

Step 2: Yarn over again and pull through

Step 3: Yarn over a 3rd time and pull through 2 loops

Step 4: Repeat steps 1 – 3 four times total for a classic bobble stitch.

Here’s where the different sizes are made, you can do just 3 repeats instead of 4 for a mini bobble and 5 repeats for a bulky bobble.
We’re making a classic bobble stitch though, so once you’ve got your repeats made you should have 5 loops on the hook… (4 for mbo and 6 for bbo)

Step 5: Yarn over and pull through all the loops on the hook

You should try to keep bobble stitches at least 1 stitch apart from each other because it keeps them looking neat and not twisting around or leaving large holes in the separation between bobble stitches.

Now here’s the thing, you can make color changes within a single bobble stitch. I use this usually to make sleeves and arm detail in my tiny Pod Puppets, but it can also be used to make things like little berries!
Steps 1, 2, and 3 can all be done with different colors. When you see a color change for a bobble stitch written down in one of my patterns it will look something like this:
[1 G/B/R (bo)]
The number tells you how many you’re making, the letters are abbreviations for colors (Green, Blue, and Red), and the “bo” tells you it’s a classic bobble stitch.
I write it like this because that’s how it looks when it’s completed, Green then Blue then Red, but it’s not actually made that way. In reality it’s made like this…

Step 1: Yarn over first with Blue, and insert hook into stitch

Step 2: Yarn over with Green and pull through

Step 3: Yarn over with Red and pull through 2 loops

Then repeating steps 1 – 3 four times total, and finishing up by pulling through with the next color in the pattern.

Usually for arms and legs in my projects I use a classic bobble stitch, meaning repeating steps 1 – 3 four times total. Sometimes I use the mini bobble stitch when I’m making something like a thumb or there are a lot of bobble stitches in one round, but a bulky bobble stitch is just a bit too big and I rarely use it.
