Monster Pencil Case Pattern

Send your little ones back to school in style with this whimsical, textured monster pouch that makes organizing pencils incredibly fun.

Every year, I promise myself I will design a fun back-to-school project before the autumn rush begins. Somehow, time always slips through my fingers like slippery yarn.

This year was different.

My daughter saw my first prototype in bright blue and orange and immediately claimed it for her school supplies. Naturally, she then requested a second one in pink and orange, which I happily whipped up in just one evening.

If you dread flimsy pencil cases that tear before midterm, you are not alone. Kids are notoriously tough on their gear, and store-bought plastic pouches rarely survive the school year.

That is where sturdy cotton yarn comes to the rescue.

This adorable monster pouch is crocheted using dense single crochet stitches. It creates a thick, durable fabric that easily withstands the daily wear and tear of backpacks.

Plus, it is incredibly cute.

Do not let the zipper insertion intimidate you. I will walk you through every single step of the sewing process with simple, stress-free instructions so you can finish this project with confidence.

Step-by-Step Instructions

Crocheting the Main Body

Using your H (5 mm) hook and the blue yarn, make a chain of 66. Carefully form a ring by slip stitching into the very first chain, making sure your chain is not twisted.

Round 1: Chain 1 (this does not count as a stitch). Work 1 sc into the next chain. Place your contrasting yarn marker into this first sc. Work 1 sc into every chain around. Do not join. (66 sc)

Round 2: Work 1 sc directly into the marked stitch. Move your marker up into this new stitch to mark the start of the round. Work 1 sc in each stitch around.

Rounds 3-11: Repeat the Round 2 process, always moving your marker up. Once you complete 11 rounds of single crochet, slip stitch into the next stitch and fasten off.

Round 12: Join your orange yarn with a slip stitch. Chain 1, work 1 sc in the next stitch, and place your marker in this stitch. Work 1 sc in each stitch around. Do not join.

Remaining Rounds: Continue working 1 sc in each stitch, moving your marker up at the start of every round. Work until your orange section matches the height of the blue section (or to your desired length). Slip stitch to the next stitch and fasten off.

Crafting the Eyes

Left Eye (Larger White Circle): Using your H (5 mm) hook and white yarn, chain 4. Slip stitch to the first chain to form a ring. Working over your starting yarn tail, chain 1. Work 8 sc into the ring, then slip stitch to the first sc. Do not turn. (8 sc)

Chain 1, work 2 sc in each of the 8 stitches. Slip stitch to the first sc. Do not turn. (16 sc)

Chain 1, *work 2 sc in the next stitch, then 1 sc in the following stitch. Repeat from * around 8 times. Slip stitch to the first sc. Fasten off, leaving a 15-inch tail for sewing. (24 sc). Pull the starting tail tight to close the center hole, then weave it in.

Right Eye (Smaller White Circle): Using your F (3.75 mm) hook and white yarn, chain 4. Slip stitch to the first chain to form a ring. Working over your starting tail, chain 1. Work 7 sc into the ring, then slip stitch to the first sc. Do not turn. (7 sc)

Chain 1, work 2 sc in each of the 7 stitches. Slip stitch to the first sc. Do not turn. (14 sc)

Chain 1, *work 2 sc in the next stitch, then 1 sc in the following stitch. Repeat from * around 7 times. Slip stitch to the first sc. Fasten off, leaving a 15-inch tail for sewing. (21 sc). Pull the starting tail tight to close the center hole, then weave it in.

Larger Pupil (Black): Using your F (3.75 mm) hook and black yarn, chain 4. Work 1 sc in the second chain from your hook, and 1 sc in the next chain. Work 3 sc in the last chain. Pivot your work to crochet along the opposite side of the foundation chain. Work 1 sc in each of the 2 free loops. Slip stitch to the beginning chain-1. Fasten off, leaving a long tail for sewing.

Smaller Pupil (Black): Using your F (3.75 mm) hook and black yarn, chain 3. Work 1 sc in the second chain from your hook, then work 3 sc in the last chain. Pivot your work to crochet along the opposite side. Work 1 sc in the free loop. Slip stitch to the beginning chain-1. Fasten off, leaving a long tail for sewing.

Making the Teeth

Note: All teeth are worked in one continuous piece. Do not fasten off between teeth.

Using your F (3.75 mm) hook and white yarn, chain 4. Slip stitch in the second chain from your hook, work 1 sc in the next chain, and 1 dc in the last chain. (First small tooth completed).

Chain 5. Slip stitch in the second chain from your hook, work 1 sc in the next chain, 1 hdc in the next, and 1 dc in the last chain. (First large tooth completed).

Chain 5. Slip stitch in the second chain from your hook, work 1 sc in the next chain, and 1 dc in the last chain. (Second small tooth completed).

Repeat these steps until you have a total of 6 teeth. Chain 1 at the corner, slip stitch along the top edge of the teeth, and fasten off, leaving a long tail for sewing.

Creating the Spikes and Legs

Spikes (Make 2 - One Blue, One Green): Using your F (3.75 mm) hook and blue yarn, chain 4. Slip stitch to the first chain to form a ring. Working over your starting tail, work 6 sc into the ring. Do not join or turn. (6 sc)

Work 2 sc in the next stitch, then 1 sc in the following stitch. Repeat from * around 3 times. (9 sc). Pull the starting tail tight to close the center hole, tie a secure knot on the wrong side, and trim the excess.

Continue working 1 sc in each stitch until the spike measures 3 inches. Slip stitch to the next stitch and fasten off, leaving a long tail for sewing. Repeat this process using green yarn to make the second spike.

Corkscrew Legs (Make 2 - One Blue, One Green): Using your F (3.75 mm) hook and blue yarn, chain 16. Work 3 sc in the second chain from your hook, then work 3 sc in every chain across. Fasten off, leaving a long tail. Repeat this process using green yarn to make the second leg.

Assembly and Sewing

First, weave in the starting tails on the black pupils. Sew the larger black pupil onto the larger white circle, aligning it near the top where the long tail emerges. Repeat for the smaller eye.

Position the completed eyes on the front of the pouch. Use the long white yarn tails to sew them securely in place. Once attached, use white thread or yarn to stitch three small lines onto each black pupil to create a glinting highlight.

Position the teeth inside the mouth area and sew along the top edge. You can also stitch down the tip of each tooth if you want them to stay perfectly flat.

Place the spikes on the sides of the pouch, tucking them slightly behind. Sew through both layers of the spike and the back layer of the pouch to secure them.

Attaching the Zipper

If your zipper is too long, sew a new stopper by wrapping sewing thread tightly around the zipper teeth several times at your desired length. Leave about an inch of zipper tape beyond your new stopper, then trim off the excess.

Insert the closed zipper into the top opening of the pouch, positioning the zipper pull near the left corner. Tuck any excess tape inside. The crocheted edge should sit right against the zipper teeth without overlapping them.

Pin the zipper in place. Use a contrasting color of sewing thread to make large basting stitches to hold it temporarily. This makes it much easier to sew neatly.

When you reach the right corner, tuck the excess tape inside and sew through all four layers (two layers of zipper tape and two layers of crochet fabric) back and forth a few times to secure.

Open the zipper. Align the back of the pouch with the zipper teeth and sew. When you return to the pull side, close the zipper, tuck the tape, and sew through all four layers at the corner just like before.

Once everything is aligned perfectly, use matching sewing thread to backstitch the zipper securely in place. Carefully pull out your contrasting basting stitches.

Closing the Base

Place a stitch marker at the bottom right corner of the pouch to mark your starting point. Open the zipper and turn the entire pencil case inside out.

Starting at your marker, slip stitch the two bottom layers together. When you have stitched about one-third of the way across, insert one of your corkscrew legs between the layers and slip stitch through it to lock it in place.

Continue slip stitching. When you reach the two-thirds mark, insert the second corkscrew leg and secure it the same way. Slip stitch to the end of the row, fasten off, and weave in all remaining ends. Turn the pouch right side out.

Easy Variations & Custom Ideas

• Monochrome Monster: Try making the entire body in a solid color if you prefer a simpler look.
• Three-Eyed Monster: Add a third eye in the center using the smaller eye pattern for an extra-silly look.
• Size Adjustments: To make a larger pouch, simply increase your starting chain in multiples of two. You can also use this technique to make a larger Crochet Makeup Bag Free Pattern.
• No-Sew Details: If you prefer not to crochet the eyes, you can use felt cutouts and fabric glue instead.
• Striped Fun: Experiment with different stripe widths or use self-striping yarn to let the colors transition naturally.
• Colour ideas: Bright neon green and purple make a fantastic, spooky combination, while pastel pink and mint offer a softer look.
• Yarn substitutions: Any worsted weight cotton or cotton-blend yarn will work beautifully for this project.

Common Troubleshooting & Fixes

• Problem: The zipper is catching on the crochet stitches.
  Fix: Make sure your crocheted edge does not overlap the zipper teeth. If it does, gently rip out your sewing stitches and reposition the zipper slightly further down.
• Problem: The bottom of the pouch looks uneven after slip stitching.
  Fix: Ensure your pouch is laid completely flat before you begin slip stitching the bottom closed. Using stitch markers to pin the corners in place helps keep everything aligned.
• Problem: Pencils are poking through the stitches.
  Fix: Your tension might be a bit too loose. Try dropping down to a smaller hook size, or line the inside of the pouch with a scrap of cotton fabric.
• Problem: The corkscrew legs are not curling.
  Fix: Make sure you are working exactly three single crochets into every single chain. This high concentration of stitches is what forces the chain to twist into a spiral.

Care Instructions

To keep your monster looking fresh and vibrant, I recommend hand washing it in cold water with a mild detergent. Lay it flat to dry to prevent the cotton from losing its shape. Avoid machine drying, as this can damage the zipper and cause the cotton to shrink unevenly.
