Step 1: Prepare the Watermelon Paper

First things first – grab your red and green paper. Cut them into equal-sized squares, around 8×8 inches works beautifully (Image 1 below).

You can use a different size of course. Keep in mind that the smaller you go, the more ‘fiddly’ it will be for young hands. You may also prefer to measure and cut to the same size of the width of your paper to make it easier.

If you’ve got origami paper, you get to skip the scissors and head straight to the fun stuff!

Glue the red paper to the back of the green paper so each side is a different color (Image 2 below). This gives you that perfect watermelon rind and juicy inside look. Let it dry for a moment so everything sticks nicely.

Step 2: Fold and Snip

Once dry, fold your square diagonally corner to corner – both ways – and then unfold it. You’ll see an “X” of creases (Image 3 above). 

Use scissors to cut along each crease from the corners toward the center, stopping about an inch before the middle.

Step 3: Add Those Watermelon Details

Now for the fun part! Flip to the red side and draw black teardrop shapes to look like watermelon seeds. 

On the green side, draw stripes or zigzags near the center to give that rind a little personality. Don’t overthink it – this is one of those cute-imperfect crafts that always turns out adorable.

Step 4: Shape the Pinwheel

If you have a handheld hole punch, use it to punch four holes – one in each corner, just to the left of where you made your scissor cuts.

Fold one diagonal in half to help you pierce the center of the paper, then do the same for the top of your straw.

If you don’t have a hole punch, don’t stress! Use the end of your paper fastener, a pin, or even a pen (grown-ups, this part is yours if little hands are involved).

Gently fold each corner with a hole toward the center of the pinwheel – don’t crease them! Hold them in place and push the paper fastener through the center hole and through all the folded corners.

Step 5: Attach the Straw

Now it’s time to bring your pinwheel to life. Push the fastener through the hole in the top of your straw.

I use paper fasteners for my pinwheels—they’re perfect for holding everything together while still letting them spin. 

If the pinwheel is pressed too tightly, it won’t have enough room to rotate, so be sure to leave a little wiggle room. 

You can also try a push pin into a pencil eraser or add a small bead spacer to help it twirl more easily. Just make sure little hands have a grown-up to help with the sharp bits!

Give it a test spin—and there you go! Fruity fun in motion.

FAQs About This Watermelon Paper Craft

How do you make a paper pinwheel that spins?

The trick is in the spacing! You want your paper fastener to be tight enough to hold everything together, but loose enough that the blades can catch the breeze. Ensure you get a fastener that’s long enough. You can also add a small bead between the paper and straw to help reduce friction.

What materials work best for a spinning pinwheel?

Lightweight paper like origami paper is the best to use. Cardstock can be too heavy and won’t spin as easily. If you’re only using one sheet of paper, then a slightly thicker patterned paper will still work. You’ll also need a straw or stick, a paper fastener or push pin, and some kind of marker for decorating (in the case of our watermelon theme!).

Can I make a pinwheel without a paper fastener (brad)?

Yep! You can use a push pin into a pencil eraser (carefully), or even twist a pipe cleaner through the center and around the straw if you just want a cute decoration that doesn’t spin.

Is this watermelon craft safe for little kids?

Totally – just make sure a grown-up helps with the scissors and sharp bits like the fastener or push pin. You can even prep the folding and holes ahead of time to make it more toddler-friendly.

Why won’t my pinwheel spin?

Most often, it’s just too tight. Try loosening the fastener or adding a bead spacer. Make sure the blades aren’t glued down or creased too stiffly. And check if the straw hole allows the pinwheel to rotate freely.

What are some fun ways to use this craft?

Aside from looking totally adorable? These are great for summer crafts for kids, 4th of July crafts, party centerpieces, outdoor play, or classroom learning about wind and weather.
