Crochet Bob the Square Sponge Hat

Who lives in a pineapple under the sea?! Yep, it’s your favorite square sponge named Bob! My son has been begging me for this hat and since I mastered the technique of crocheting a square hat (thanks to my Robot pattern), I had to get Mr. Squarepants on my hook immediately :)

Materials:
– Worsted Weight Yarn. I used Lion Brand Vanna’s Choice in Duckie (yellow), White, and Honey (brown) with a bit of red, black, and turquoise for the eyes, cheeks, mouth, and tie.
– Size H crochet hook
– Tapestry needle

Abbreviations:
Magic Ring Tutorial
SC = Single Crochet
SC Decrease = Single Crochet Decrease
DC = Double Crochet

Before you get started I recommend watching this video on how to stitch on eyelashes. Apply this technique when stitching on other face embellishments like the mouth and cheeks. And be kind to yourself! Even I had a couple do-overs :)

Now you can begin to stitch on the other elements using your tapestry needle. Stitch on the belt, mouth, cheeks, and eyelashes. I also stitched a border of black around each eye as I was making the eyelashes. Remember to watch the video above or you can watch my video on how to sew on a puppy nose and mouth (below) for more help.

Is it just me or is anyone else having issues with the 1st video? The one that says to watch this video on stitching on eyelash technique? There is nothing for me to click on & I don't see a video except for at the bottom which is the puppy dog one…

Hi Sarah,
I’m from Australia and worsted weight yarn isn’t that popular here – can I just increment the foundation chain by multiples of two as you have between sizes until I get it to the right size? Thanks!
