Supplies You’ll Need for These Polymer Clay Magnets

Before diving into your Valentine’s Day creations, gather all the necessary supplies. You’ll need polymer clay in festive colors—think reds, pinks, whites, or even a trendy pastel palette.

A rolling pin or acrylic roller will help flatten your clay evenly, and small cookie cutters or sculpting tools will make shaping a breeze. If you want to freehand your designs, a craft knife or clay cutter is essential for precision.

To turn your clay creations into magnets, you’ll need small, strong magnets and a reliable glue (super glue or E6000 works well).

Want to add a little extra flair? Consider embellishments like mica powder, glitter, or a glossy varnish to give your magnets a polished, professional finish.

3 Valentine’s Day Polymer Clay Magnet Ideas

Handmade magnets make for adorable mini Valentine’s Day gifts—whether you’re crafting for a partner, a friend, or just yourself! These three ideas are simple yet stylish, perfect for beginners and experienced crafters alike.

1. Mini Love Letter Magnet 💌

Nothing says romance quite like a love letter, and this tiny polymer clay version makes for the cutest magnet! Start by rolling out a thin piece of white or pastel-colored clay and cutting it into a small rectangle.

Fold it into an envelope shape, leaving the top flap slightly open. For an extra sweet touch, add a tiny red or pink clay heart as a seal. Watch the full tutorial to see how you can add a cute little bouquet of roses in the letter.

If you want to go all out, you can use a fine-tip tool to imprint small details, like the recipient’s initials or a tiny “XO” message. Once baked, attach a magnet to the back and seal it with a thin layer of varnish for a polished look. Stick it on your fridge or gift it with a handwritten note to complete the theme!

2. Heart-Shaped Doughnut Magnets 🍩

What’s sweeter than a Valentine’s Day treat? A heart-shaped polymer clay doughnut magnet that looks good enough to eat! Start by rolling out some tan or light brown polymer clay and cutting out a small heart shape.

Use a smaller cutter or a sculpting tool to remove the center for that classic doughnut look. Next, roll out a thin layer of pastel pink, red, or white clay for the icing and drape it over the top, letting the edges appear slightly “drippy.”

Add tiny clay sprinkles in festive colors like red, pink, and white—just roll tiny bits of clay into sprinkles or shape them into tiny hearts!

For an extra realistic effect, gently texture the doughnut base with a toothbrush before baking to give it that soft, fried look. Once baked and cooled, attach a magnet to the back and seal the icing with a glossy glaze to mimic real frosting.

These adorable miniature doughnut magnets are the perfect way to add a touch of sweetness to your fridge or gift to a fellow dessert lover!

3. Love Potion Magnets 🧪

These whimsical love potion bottle magnets are perfect for Valentine’s Day! Start by shaping a small glass-like bottle from translucent or white polymer clay.

You can make it rounded, like a potion vial, or go for a classic potion bottle shape with a wider base and a narrow neck.

For the bottle stopper, roll a small ball of clay and press it onto the neck of the bottle. You can also add a tiny clay label with cute phrases like “Love Elixir” or “Potion No. 14” using a fine-tip tool or paint after baking.

Once baked, attach the magnet to the back and seal with a glossy glaze or UV resin to make the bottle look like it’s made of real glass. These charming love potion magnets are a fun, fantasy-inspired Valentine’s Day gift that will add a little magic to any space!

Tips for Baking and Sealing Your Polymer Clay Magnets

Getting the perfect finish on your polymer clay magnets comes down to baking and sealing them correctly. Always bake your clay at the right temperature according to the brand’s instructions—typically around 230°F–275°F (110°C–135°C) for 15–30 minutes, depending on thickness.

Overbaking can lead to discoloration, so keep an eye on your pieces! Once your magnets have cooled completely, it’s time to attach the magnets using a strong adhesive. E6000 glue is a great option for a secure hold.

If you want a professional touch, finish your magnets with a satin or glossy glaze or even UV resin for a glassy, candy-like effect. These little details will make your Valentine’s Day magnets look like mini works of art!

Final Thoughts & How to Gift Your Handmade Magnets

Polymer clay magnets make for charming and heartfelt Valentine’s Day gifts, and the best part is—they’re totally customizable! You can package them in a small gift box with a bit of tissue paper for a thoughtful presentation.

Want to take it up a notch? Attach the magnet to a DIY Valentine’s Day card for a creative and interactive gift. If you’re making a set, you can even pair them with a handmade polymer clay trinket dish or a small personalized note.

No matter how you choose to gift them, these magnets are a sweet and stylish way to spread a little love this Valentine’s Day. 💕
