How to Make a Party Hat for a Baby

Looking to make a party hat for a baby? I have nearly ten years of experience making hats for first birthday parties and beyond. Below is a detailed tutorial with step-by-step pictures, and I also include a birthday hat template that you can download for free.

When our son was approaching his first birthday, I searched high and low for baby’s first birthday party ideas, decorations, outfits, food, you name it. It was the summer of 2011, and my big goal was to handcraft everything for his party. I wanted to make it all from the invitations to the thank you tags, the food signs, and a first birthday party hat. And I did!

I didn’t know how to make a party hat, but I figured it couldn’t be hard to make. So, I searched blogs for 1st birthday party hats and everything else under the sun and got super inspired!

Turns out, our baby’s first birthday party – and all of its decor- was a great success. Our baby’s 1st birthday hat was my personal favorite. Later that year, my friends started calling me to make their parties’ decorations, too. This is how my Etsy business -and eventually, my blogs- started.

So, without further ado, here’s my step-by-step tutorial on making a 1st birthday hat and how you can modify it to fit older kids and adults.

Supplies Needed to Make a Party Hat

Step 1. Print and Cut the Template

Print the party hat template on white paper. For a sturdier template that is easy to handle and lasts longer, print on 110 lb. white cardstock.

Step 2. Trace the Template on Cardstock

Lay the cutout template on the cardstock you choose for the party hat, and trace the outline.

You can use this template to make party hats for both adults and babies. Party hats sit on top of the head; they do not cover the entire head. You will only have to adjust the length of the tying ribbons accordingly. (As explained in step 7).

Step 3. Cut the party hat

With a pair of scissors, simply cut around the party hat you traced. Set aside the leftover cardstock.

In the template, you will notice there is a line across from the tab. This line is your guide to cutting a slit if you prefer to insert the party hat’s tab inside to secure it. I personally do not use it and prefer to overlap the edge over the tab.

I do not insert the tab inside the slit because the cardstock tends to be heavy and pulls away, opening the hat. Therefore, I like to overlap and secure it with hot glue. See the next step.

Step 4. Bend into a Cone and Glue the Hat

Slightly bend the cardstock to create the cone. See how the cardstock has taken the shape of a cone, but I let go.

Turn on the hot glue gun, and wait until the glue is hot and melting, almost oozing off the tip of the glue gun. Hot glue dries almost instantly, so you will need to work fast in this step.

Squeeze a line of hot glue on the tab, grab the other end of the cone, and place it right over it. Make pressure, so both ends adhere. The hot glue will dry in seconds. Now you have the cone for your DIY party hat.

Optional Step

Sometimes after overlapping, the seam on the party hat is not pretty, so I cover it with a thin strip of ribbon in the same color as the cardstock. This step isn’t necessary; it just makes a better finish, especially if you are planning to sell the party hats, as I do in my Etsy shop.

Step 5. Prepare the Pom-Pom

Cut a 12-inch string of cotton twine, and tie a small knot on one end of the string. Thread the other end through the needle.

Push the needle through one side of the pom-pom until it comes out from the opposite side. The knot will stop the string from going through the pom-pom. The knot gets buried in the pom-pom; you won’t see it.

Step 6. Attach the Pom-pom to the Party Hat

After shaping the party hat, you will notice that there is a very small opening on the top of the cone.

With the string still threaded in the needle, and the pom-pom hanging on the other end of the string, drop the needle through the small top hole of the hat.

Pull the string from the other side, remove the needle, and secure the string tightly with a small piece of clear tape. The pom-pom will sit on top of the hat, but it will sit wobbly.

Secure the pom-pom to the party hat with small dots of hot glue.

Step 7. Cut the pieces of ribbon

For this step, you need to cut 3 pieces of ribbon.

The first piece will wrap around the round perimeter of the cone. For this particular party hat template, you will need 15 inches. You can add a little more (and then trim the excess) but no less than 15 inches.

The other two pieces will be the party hat ties. The length of these two pieces of ribbon will depend on who will be wearing the hat. If you are making a 1st birthday hat, 20 inches for each piece is more than enough ribbon to tie, and make a bow, even.

These DIY party hats are designed to sit ‘on top of the head’, and they do not need to cover the entire circumference of the head. What you will need to do is adjust the length of the ribbon ties.

If you are making hats for adults, measure yourself and calculate how much ribbon you will need to tie the party hats under the chin of an adult.

Step 8. Trim the Party Hat

Time to trim your DIY party hat.

I used hot glue to attach the trim to the party hat. I would work in sections, slowly squeezing hot glue around the cone’s edge and attaching the ribbon.

This method works perfectly fine; if you are careful, the trim on your hat will be just perfect. However, I now use a different method.

Optional Method: Use a Sticker Maker

Push the 15-inch piece of ribbon through the (optional) sticker maker, this will make a sticky backing. With a sticky backing, attaching the ribbon to the party hat becomes a much easier, cleaner, and faster method.

Step 9. Attach the Ribbon Ties to the Hat

As a reminder, make sure to measure these two pieces of ribbon to ensure they will fit the person that will be using the hat. If this is a party hat for a baby’s first birthday, you will need the two pieces to be no less than 20 inches long each.

Find the front of the party hat (seam facing the opposite side) and proceed to punch a small hole on each side of the party hat with the 1/8-inch punch.

Thread the ribbon through the hole and tie a small knot on the ribbon’s end that is inside of the hat.

Pull the string until the knot stops it.

Step 10. Optional: Add Embellishments

At this point, your baby’s 1st birthday hat is done. However, I always like to add embellishments that make these hats unique. Depending on the baby’s birthday theme, the hat will feature a number 1 or anything else my customers like.

Whatever you decide to add to the hat is up to you! Scrapbook embellishments, ribbons, buttons, and even stickers, make the party hats extra special. Another option to add some pizzaz to your baby’s party hat is to use patterned cardstock in lieu of solid cardstock.

Now you know how to make a party hat for a baby or any other occasion, and the possibilities are endless.

Happy crafting,
