Capture a little piece of nature you can carry everywhere 🌸✨

There’s something so special about turning real flowers into tiny keepsakes you can use every day. These pressed flower resin keychains are simple to make, wonderfully customizable, and such a fun way to preserve blooms from your garden, a special trip, or even a meaningful bouquet.

Using UV resin makes this project especially beginner-friendly because it cures quickly under a UV lamp, so you don’t have to wait hours for your creations to harden. And when you pair it with beautifully pressed flowers, it’s like preserving a tiny moment of nature forever.

Let’s make some!

What You’ll Need

• Pressed flowers

• Handcrafter UV Resin

• Clear silicone keychain molds

• UV lamp

• Glitter, mica powder, or UV resin colorants (optional)

• Toothpicks or craft sticks

• Mixing cup

• Lighter (optional, for popping surface bubbles)

• Keychain hardware or lobster clasp attachments

Why Clear Molds Matter for UV Resin

One important tip before you start: when using UV resin, clear silicone molds work best.

Because UV resin cures with light, the UV lamp needs to penetrate through the mold to harden the resin evenly. Clear molds allow the light to reach all sides, helping your keychains cure faster and more completely.

Colored molds can block the light, which may leave areas sticky or uncured and require multiple rounds under the lamp.

Step 1: Mix Your Resin Layer

Start by pouring a small amount of UV resin into a mixing cup.

If you’d like a little sparkle, this is the perfect time to add glitter, mica powder, or translucent colorants. You can also purchase pre-colored UV resin if you want an easy shortcut.

A little goes a long way here! If your mixture gets too thick with glitter, simply add more resin to thin it out.

Tip: Avoid using completely opaque colorants. UV light needs to travel through the resin to cure it properly.

Step 2: Create the Background Layer

Pour a thin layer of resin into the bottom of your mold.

Use a toothpick to spread the resin evenly and guide it around the small center post that creates the keychain hole.

This is also a great time to remove bubbles. Tiny bubbles often hide along the edges or corners of the mold, so gently lift them out with a toothpick and wipe the excess away on a paper towel.

Once the layer looks smooth, place the mold under your UV lamp and cure it.

Step 3: Secure Your Pressed Flower

After the first layer has cured enough to work with, add another very thin layer of clear resin.

This layer acts like glue for your flower.

Carefully place your pressed flower into the resin. Try to touch the flower gently in the center or along sturdy edges rather than poking delicate petals, which can create dark or “wet” spots.

If you fill the mold completely before placing the flower, the bloom may float to the top. A thin layer helps keep everything beautifully positioned.

Once your flower is arranged the way you like it, cure it briefly under the UV lamp just long enough to hold it in place.

Step 4: Add the Final Resin Coat

Now it’s time to seal your flower inside the keychain.

Slowly pour clear resin over the flower until the mold is filled nearly to the top. Go carefully here — overfilling can cover the keychain hole or create extra cleanup later.

Let the resin settle naturally before adding more. Resin has a lovely surface tension that allows it to slightly “dome” above the mold edge for a smooth, rounded finish.

A gently domed top helps prevent sharp edges after curing.

As you work, keep an eye out for trapped bubbles, especially around layered petals or flower centers. Give the resin a little time so hidden air bubbles can rise to the surface.

For larger bubbles:

• Lift them with a toothpick

• Or carefully pass a lighter quickly over the surface

Just don’t hold the flame in one place too long, as it can damage the mold or scorch the resin.

Step 5: Cure Completely

Place your keychain under the UV lamp for a full curing cycle.

Check the surface carefully afterward. If it still feels tacky or slightly concave, add another thin layer before removing it from the mold.

Because UV resin can sometimes pull slightly toward the mold edges as it cures, inspecting it before demolding helps you catch any low spots or missed bubbles.

If you used heavy glitter, curing the piece upside down for one final round can help ensure the back is fully hardened too.

Step 6: Demold & Add Hardware

Once fully cured, gently peel the silicone mold away from your resin piece.

And there it is — your beautiful pressed flower creation! 

Attach your keychain hardware by feeding the loop through the molded hole and securing it onto the split ring or lobster clasp.

These little botanical treasures aren’t just for keys either. They also make lovely:

• Bag charms

• Zipper pulls

• Purse accessories

• Backpack charms

• Tiny handmade gifts

Creative Ideas to Try

One of the best parts about resin keychains is how customizable they are. You can experiment with:

• Tiny wildflowers for a delicate cottagecore look

• Bright petals and glitter for playful sparkle

• Wedding bouquet blooms for meaningful keepsakes

• Seasonal flowers like spring blossoms or autumn leaves

• Gold flakes or mica powder for elegant accents

There’s no single “right” way to create these — every flower tells its own story.

Final Thoughts

Pressed flower resin keychains are such a joyful way to preserve nature in a form you can carry every day. Whether you’re making gifts, memorial keepsakes, or simply creating for fun, each piece feels like a tiny window into a beautiful moment.

And because UV resin cures so quickly, you can make several at once and enjoy the process without the long wait.

You’ll love how magical it feels to turn a simple flower into something lasting, colorful, and completely unique.
