DIY Toddler Pillowcase for 13×18: A Complete Sewing Guide for Parents

If you’ve ever gone shopping for a toddler pillowcase only to walk away empty-handed — or worse, paying far too much for something your child will outgrow or destroy in a matter of months — you already know the frustration. Standard pillow sizes don’t always translate to toddler bedding, and the 13×18 toddler pillow is a perfect example. It’s small, it’s specific, and the ready-made pillowcase options are often limited in design and overpriced for what they are.

The good news is that sewing your own DIY toddler pillowcase for a 13×18 pillow is one of the easiest beginner sewing projects out there. You don’t need a fancy machine or advanced skills. You don’t even need a pattern. With about half a yard of fabric and thirty minutes of your time, you can create a soft, adorable, and completely washable pillowcase your toddler will love. And once you’ve made one, you’ll find yourself making five more in every fabric print you can find.

This guide walks you through everything: the materials you need, how to cut your fabric, two different sewing methods, tips for choosing safe and soft fabrics for toddlers, and ideas for personalizing the pillowcase to make it extra special. Whether you’re a seasoned seamstress or someone who just dusted off a sewing machine for the first time, this tutorial is for you.

Why a 13×18 Toddler Pillow?

Before we get into the sewing, it helps to understand why the 13×18 size matters. Most adult pillows are 20×26 (standard), 20×30 (queen), or 20×36 (king). These are far too large for a toddler’s body and sleeping space, and using adult-sized pillows for young children actually poses a safety risk, particularly for children under two years old.

The 13×18 toddler pillow is designed to fit a toddler’s smaller head and neck proportions. It’s used in toddler beds, cots, and floor-level mattresses, and it travels well in strollers and cars. Because it’s a non-standard size, however, finding a pillowcase to fit it can be surprisingly difficult. Most pillowcase sets sold at big box stores are designed for standard or queen sizes. A toddler pillowcase sewn specifically for a 13×18 insert is the ideal solution, and making it yourself means you control every detail, from the fabric softness to the closure style.

What You’ll Need

Here is everything you’ll want to have on hand before you begin. Most of these items are either already in a basic sewing kit or easy to find at any fabric or craft store.

Fabric: You’ll need about half a yard (18 inches) of 44- to 45-inch wide quilting cotton or similar fabric. One single piece is enough for the simplest version of this pillowcase. If you want to add a contrasting cuff or border, you’ll need a small additional piece in a coordinating print or solid.

Sewing machine: A basic home sewing machine with a straight stitch is all you need. No special feet or attachments are required.

Thread: Use a thread color that matches or complements your fabric. For a 100% cotton fabric, an all-purpose cotton or polyester thread works perfectly.

Scissors or rotary cutter: Fabric scissors work fine. A rotary cutter and cutting mat make the process faster and give you cleaner, straighter edges.

Ruler or measuring tape: Accuracy matters here, even just a little. A clear quilting ruler is especially helpful.

Iron and ironing board: Pressing your seams makes a significant difference in the final look. Don’t skip this step even if you’re in a hurry.

Pins or clips: Fabric clips are easier to work with than straight pins, especially for beginners.

Optional: A fabric marker or chalk for marking cutting lines.

Choosing the Right Fabric for a Toddler Pillowcase

Fabric choice matters more for a toddler pillowcase than it does for most home sewing projects, because this item will be in direct contact with your child’s face while they sleep. There are a few things to keep in mind.

Softness: Quilting cotton is a popular choice because it’s widely available, easy to sew, comes in thousands of prints and colors, and softens beautifully with washing. Flannel is another excellent option, particularly for cooler months, because it feels cozy and warm against the skin. Jersey knit fabric, which is the same material as most t-shirts, is wonderfully soft and stretchy, though it requires a bit more attention when sewing because it can shift and stretch.

Safety: Look for fabrics labeled as OEKO-TEX certified or made from organic cotton. These have been tested for harmful substances and are considered safe for sensitive skin. Avoid fabrics with heavy coatings, stiff finishes, or synthetic blends that don’t breathe well, as these can trap heat and cause discomfort.

Washability: A toddler pillowcase needs to withstand frequent washing. Pre-wash your fabric before you sew to prevent shrinkage later. Cotton and flannel both hold up extremely well over time with regular laundering.

Fun prints: One of the best parts of making your own toddler pillowcase is getting to choose a fabric that reflects your child’s personality. Dinosaurs, rainbows, farm animals, outer space, trucks, flowers, cartoon characters on licensed fabrics — the options are endless. Let your toddler weigh in if they’re old enough. Having a pillow covered in their favorite thing makes bedtime just a little more exciting.

Measuring and Cutting Your Fabric

For a 13×18 toddler pillow, you’ll need to cut your fabric to specific dimensions depending on which construction method you’re using. Here are the two most common approaches.

Method One: The Simple Fold-Over (No-Cuff) Pillowcase

This is the fastest and most straightforward method. You’ll sew the pillowcase from a single piece of fabric folded in half.

Cut one piece of fabric measuring 14 inches wide by 42 inches long. The 14-inch width gives you a half-inch seam allowance on each side, and the 42-inch length allows the fabric to fold in half to create a pocket that fits a 13×18 pillow with a 3-inch tuck-in flap.

Method Two: The Burrito or Roll Method (With Cuff)

This classic pillowcase construction method creates a pillowcase with a decorative cuff at the open end. It produces a more polished, professional-looking result and is actually easier to sew than it sounds.

For this method, cut two pieces of fabric. The main body piece should measure 14 inches wide by 28 inches long. The cuff piece should measure 14 inches wide by 10 inches long. If you want a contrasting cuff, cut the cuff from a different fabric. The combined length gives you a finished pillowcase that comfortably fits a 13×18 pillow with a clean, finished opening.

Sewing the Pillowcase: Method One

This method is perfect if you want to finish quickly and don’t need a decorative cuff.

Start by folding your fabric in half with the right sides facing each other. The fold itself will become the closed bottom end of the pillowcase, so you don’t need to sew that edge. Your raw edges should be at the top and along the two sides.

Pin or clip the two long side edges and the short open edge together. Using a half-inch seam allowance, sew down one long side, across the short open end, and back up the other long side. Backstitch at the beginning and end of your seam to lock it in place.

To prevent fraying and create a durable edge that holds up through washing, either zigzag stitch along your raw edges, use a serger if you have one, or fold and press a narrow hem before stitching. Clip the corners diagonally at the two sewn corners (the bottom corners when the pillowcase is open), which will allow those corners to lie flat and sharp when the pillowcase is turned right side out.

Turn the pillowcase right side out, gently push the corners out with a blunt tool (a chopstick works great), press with an iron, and you’re done. Insert your 13×18 pillow through the open end. The extra fabric folds back inside to keep the pillow in place.

Sewing the Pillowcase: Method Two (The Burrito Method)

This method gets its name from the way you roll the fabric up like a burrito before sewing the cuff seam. It sounds complicated but is very satisfying once you try it.

Begin by pressing your cuff piece in half lengthwise with the wrong sides together so it forms a long narrow strip 5 inches wide and 14 inches long. Set it aside.

Lay your main fabric piece flat with the right side facing up. Place the folded cuff piece along one of the short ends of the main fabric, aligning the raw edges of the cuff with the raw edge of the fabric. All raw edges should be at the same end.

Now, starting from the opposite end of the main fabric (the end without the cuff), roll the fabric tightly toward the cuff end, rolling it up like a burrito. Stop rolling just before you reach the cuff.

Bring the folded edge of the cuff up and over the rolled body of the fabric, encasing the roll completely inside the cuff. The raw edges of the cuff should align with the raw edges of the main fabric underneath. Pin through all the layers.

Stitch across this end using a half-inch seam allowance, sewing through all layers. When you’re done, gently pull the rolled fabric out through the open tube end. The pillowcase will unfurl and the cuff will be cleanly sewn in place with no raw edges showing.

Press the cuff flat so the folded edge extends outward from the pillowcase body. Fold the remaining three sides of the main fabric piece in half with right sides together (the cuff should now be tucked inside), and sew down the long sides and across the short closed bottom using a half-inch seam allowance. Finish raw edges, clip corners, turn, and press.

The result is a beautiful pillowcase with a finished decorative cuff at the opening, exactly like the kind you see in boutique toddler shops for three times the price.

Finishing Touches and Personalization Ideas

A plain pillowcase is lovely, but there are so many easy ways to make it feel truly special. Here are a few ideas that don’t require advanced sewing skills.

Embroidery: A simple embroidered initial or small design on the cuff or front of the pillowcase makes it feel personalized and gift-worthy. Iron-on stabilizer makes embroidery on fabric much easier for beginners. You can also use embroidery iron-on transfers if you’re not confident drawing designs freehand.

Iron-on appliqué: Fusible web appliqué is a no-sew way to add shapes, animals, or letters to your pillowcase before you sew it. Cut your shape from fabric, iron it to the pillowcase front using fusible web, and optionally stitch around the edges for durability.

Fabric paint or stamps: Fabric-safe paints and foam stamps let you add polka dots, handprints (a toddler’s handprint is an especially sweet keepsake idea), or other patterns to a plain fabric before sewing.

Ribbon or trim: A strip of ribbon, rickrack, or decorative trim sewn along the cuff seam adds a charming finishing detail with almost no extra effort.

Name or phrase: If you have access to a home embroidery machine or a vinyl cutting machine, adding a child’s name to the pillowcase makes it an excellent personalized gift for birthdays, baby showers, or holidays.

Care Instructions for Your Handmade Toddler Pillowcase

One of the great benefits of making a pillowcase from quilting cotton or flannel is that it’s completely machine washable. Wash in cold water on a gentle cycle and tumble dry on low. Avoid high heat, which can cause the fabric to shrink or the thread to weaken over time.

If your pillowcase has embroidery or iron-on appliqué, turn it inside out before washing to protect the design. Remove it promptly from the dryer and either fold or press it while still slightly warm to prevent wrinkles from setting.

A well-made toddler pillowcase washed with care will last for years and can even be passed down to younger siblings.

Making Multiple Pillowcases: Tips for Batch Sewing

Once you’ve made one pillowcase, you’ll quickly realize how easy it is to make more. Batch sewing is a great way to build a rotation of pillowcases so you always have a clean one ready while another is in the wash.

Cut all your fabric pieces for multiple pillowcases at once before sitting down at the machine. Chain sewing, which means feeding pieces through the machine one right after another without cutting the thread between them, speeds up the process considerably. Press all your seams at one time rather than pressing after each individual step.

With a small stack of fun fabrics, an afternoon of sewing can yield four to six pillowcases, which is enough to build a complete rotation or to wrap up as handmade gifts for every toddler in your family and friend group.

Gifting a Handmade 13×18 Toddler Pillowcase

A handmade toddler pillowcase is one of the most practical and heartfelt gifts you can give to a new parent or a family with young children. It’s lightweight, easy to ship, useful from day one, and it shows genuine thoughtfulness. Pair it with a coordinating 13×18 pillow insert and you have a complete, ready-to-use gift that would cost significantly more if purchased at a boutique.

For baby showers, consider making the pillowcase in a neutral print that works for any gender, or ask the parents about their nursery theme and tailor the fabric accordingly. For birthdays, letting the child choose their own fabric makes the gift feel extra meaningful and exciting.

Wrap it with a ribbon, tuck a card inside with washing instructions, and you have a beautifully personal handmade gift that will be used and appreciated every single night.

Final Thoughts

Making a DIY toddler pillowcase for a 13×18 pillow is one of those sewing projects that offers the perfect balance of simplicity and reward. It takes very little time, requires almost no materials, and produces something genuinely useful that you’ll use every day. For beginner sewists, it’s an ideal confidence-building project. For experienced makers, it’s a satisfying quick win that lets you use up fabric scraps and create something beautiful with minimal effort.

Whether you’re making one for your own toddler, stocking up for future use, or building a collection of handmade gifts, the process is the same: a little fabric, a little time, and the pleasure of making something with your own hands. Once you see how easy it is, the only question you’ll ask yourself is why you didn’t start sooner.
