You've probably been there. You buy a pack of those flimsy adhesive strips at the craft store, peel off the backing, and stick them to a cute ceramic tile or a heavy photo frame. Two hours later? Clatter. It's on the floor.
Making do it yourself magnets seems like a no-brainer, but most people treat magnetism like it's just "sticky metal." It isn't. Magnetism is physics. If you don't respect the pull force or the surface tension of your glue, you're just making future trash. Honestly, the biggest mistake is overestimating the strength of flexible rubber magnets. They’re fine for a business card, but they’re useless for anything with real weight.
The magnet strength spectrum most people ignore
When you start looking into do it yourself magnets, you’ll hit a wall of choices. Ceramic? Neodymium? Flexible sheet? Most hobbyists grab whatever is cheapest, but that’s a recipe for disappointment.
Ceramic magnets (ferrite) are those chunky grey blocks. They’re cheap. They last forever. They also have a relatively low "pull" compared to their size. If you’re making something vintage-looking or bulky, these are your best friend. But they chip. If they slam against the fridge too hard, they leave little grey streaks or just shatter into dust.
Then there’s Neodymium. These are the silver "rare earth" magnets. They are terrifyingly strong. A tiny disc the size of a pill can hold up a thick calendar. But here’s the kicker: they’re almost too strong for some glues. If the bond between the magnet and your craft isn't stronger than the magnetic pull to the fridge, the magnet stays on the fridge and your craft falls off.
Why your glue is actually the problem
You can't just use a school glue stick. Even hot glue—the holy grail of DIY—is often a failure point here. Because magnets are non-porous and usually smooth, glue has nothing to "grab."
Professional makers usually swear by E6000 or a high-quality cyanoacrylate (super glue). But even then, you have to prep the surface. If you don't scuff the back of the magnet with some sandpaper, the glue is just sitting on the surface like water on a waxed car. Scuff it. Clean it with isopropyl alcohol. Then glue it. It makes a world of difference.
Creative do it yourself magnets that don't look cheap
Most DIY projects look, well, DIY. But you can actually make high-end decor if you change your materials.

Take glass cabochons. You’ve seen them—those clear half-spheres. If you print a high-resolution photo, use a tiny bit of Diamond Glaze to seal the paper to the glass, and then attach a strong neodymium magnet to the back, you get a 3D magnifying effect. It looks like something you’d buy at a boutique museum shop for twenty bucks.
Another sleeper hit? Old typewriter keys. Or vintage hardware. I once saw a guy take old brass plumbing fixtures, grind them flat, and turn them into magnets. They were heavy, so he had to use 1/2-inch thick ceramic magnets. They looked incredible because they had "weight" to them, both physically and visually.
The "invisible" magnet trick
If you’re working with wood, you can actually hide the magnet entirely. This is the pro move. You drill a "forstner" hole into the back of the wood—not all the way through, just enough to leave a thin veneer of wood on the front.
Drop a strong neodymium magnet into that hole and epoxy it in place. Now, you have a piece of wood that magically sticks to metal. No visible silver disc. No glue globs. Just a clean, minimalist look. This works great for key holders or knife racks, though you’ll need much larger magnets for those.

Safety stuff no one likes to talk about
We have to talk about the "rare earth" magnets again. If you have kids or pets, neodymium magnets are a serious hazard. If two are swallowed, they can attract each other through intestinal walls. It's a medical emergency.
Also, they snap. If you have two large neodymium magnets and they jump toward each other, they can pinch your skin hard enough to draw blood or literally shatter upon impact. Shrapnel in the eye is not a fun DIY Saturday. Always slide them apart; don't try to pull them straight off each other.
The magnetic surface matters too
Not all fridges are created equal. Modern stainless steel is often non-magnetic. It depends on the nickel content. Before you spend forty hours on do it yourself magnets, take a cheap kitchen magnet and test your surface. If it slides down slowly, your "stainless" steel has a high nickel content, and you’re going to need much stronger magnets than you planned.
Better ways to source your materials
Don't buy those tiny "craft" packs at big-box retailers. They are marked up 400%.
Instead, look for industrial suppliers or bulk sellers online. You can get 100 neodymium discs for the price of 10 at a hobby store. For the "stuff" you're sticking to them, think outside the box:
- Bottle caps: Classic, but try to find vintage ones or ones from local craft breweries.
- Enamel pins: Just snip the pin off the back with wire cutters, file it flat, and glue a magnet on.
- Polished stones: If you go to the beach or a river, look for flat, smooth stones. They have a great organic feel.
- Scrabble tiles: Great for leaving "magnetic" messages or spelling out names.
Technical considerations for weight
The "Pull Force" listed on magnet packaging is a "best-case scenario." That number assumes the magnet is touching a thick, flat plate of steel. Your fridge door is thin sheet metal covered in paint. The paint creates "air gap" distance. Every millimeter of paint or paper between the magnet and the metal reduces the holding power exponentially.
If you're making a magnet that needs to hold up a heavy card or a stack of take-out menus, double your expected pull force.
To get the best results with your next project, start by organizing your materials based on the weight of the object. For lightweight paper or photos, flexible magnetic tape is sufficient, provided you apply it to at least 50% of the surface area to prevent curling. For medium-weight objects like plastic figurines or small wooden blocks, use 12mm ceramic discs paired with a multi-surface adhesive like E6000. For heavy or functional items, opt for Grade N42 neodymium discs, but ensure you countersink them into the object to provide mechanical support for the glue bond. Always clean the bonding surfaces with alcohol to remove oils that cause adhesive failure.
