I wanted a glowing cat sign above my desk for months, but every shop-made neon sign I liked cost between a hundred and eighty and two hundred and fifty euros, which is far more than I will spend on wall decoration. So I started bending LED neon flex myself, and my first attempt was a mess: I glued the flex to acrylic with super glue, which fogged the whole backing white, and the cat ears came out lopsided. Three signs later I had worked out the method, silicone adhesive instead of super glue, a printed template under the acrylic, and a dimmer on every sign. These ten projects are the ones I made in my flat, cheapest first, and none of them cost more than thirty euros.
1. The Pastel Pink Cat-Ear Outline Frame
The cat-ear outline was my first successful sign, and it is still the one I recommend starting with: just two triangles and a curved base, nothing that punishes a shaky hand. I printed the outline at full size, taped it behind acrylic, and bent two metres of pink LED neon flex along the lines, fixing it with small dabs of silicone adhesive, letting each section set ten minutes. The whole sign cost about twenty-two euros, and it hangs above my desk on two small adhesive hooks.
On my first attempt I bent the flex too tightly at the ear tips, which kinked the silicone tube and left a dark gap in the glow I could never fix. On the second try I warmed the flex with a hair dryer before tight bends, and the ears came out smooth and even. It runs from a USB plug with a small dimmer, so at night it glows softly instead of glaring, and Mimi sits beneath it most nights as if she approves.
2. “Meow” Cursive Script with Feline Tail Flourish
The cursive Meow script is the hardest sign on this list, and I only attempted it after four simpler shapes, because flowing letters hide no wobble. I printed the word in a large script font, taped it behind the acrylic, and traced it slowly with warm-white flex, leaving the final tail to curl into a flourish like a cat’s tail. The hardest part was letter spacing, because flex has a minimum bend radius, so I chose a loose, open script rather than a tight one.
I used silicone LED neon flex rather than EL wire, and that choice matters: EL wire is thinner and cheaper, but dimmer, and it breaks if bent sharply, while flex gives a smooth, bright line that reads as real neon from across the room. The finished sign is about sixty centimetres wide, cost twenty-eight euros, and hangs in my hallway where visitors see it first. If a letter goes wrong, peel it off while the silicone is soft and redo it.
3. Sleeping Curled Cat Crescent Silhouette
The sleeping crescent hangs above my bed, a curled cat silhouette on a crescent moon, bent from one length of warm-white flex with a small pink section for the ear. I drew the curled shape freehand first, then refined it three times, because a sleeping cat only reads as a cat if the curve of the back and the tuck of the paws are right, and my first sketch looked like a croissant. The finished piece is quiet and soft, and on its dimmest setting it works as a night light.
I mounted it on a pale wooden backing board rather than clear acrylic, which changed the whole feel: the wood catches a warm halo around the flex, and the sign looks handmade in the best way. It runs on a plug timer, on at sunset and off at midnight, and draws so little power I never notice it on the bill. Mimi, fittingly, sleeps curled up directly below it most nights.
4. Dual-Tone Pink & Cyan Glowing Paw Print
The paw print in two colours was my first attempt at mixing colours, pink for the main pad and cyan for the toes, and it taught me two colours means two separate power feeds. I bent the pink pad first, then the cyan toes, joining them on the backing board with a small gap between colours so light does not bleed between them. Each colour has its own short flex length and dimmer wire, joined into one USB plug with a tiny splitter, for about twenty-six euros total.
The gap between colours is the detail that makes this sign work: on my first try I butted pink and cyan together and the boundary turned into a muddy purple smear. Leaving five millimetres of dark backing between them keeps both colours clean, and from the door the print reads instantly as a paw. It hangs beside my bedroom mirror, and friends photograph it most, probably because the colour split looks more complicated than it was.
5. Geometric Wire-Mesh Cyber Cat Face
The cyber cat face is the most angular sign I made, a geometric cat head built from straight flex segments on wire mesh backing, with triangle ears and a sharp muzzle, suiting the desk corner where my laptop sits. I planned it on graph paper, marking every angle, because straight segments punish sloppy measuring far more than curves, cutting the flex to length per segment rather than bending one long piece around corners. The black mesh makes the warm-white lines stand out sharply, almost like a circuit diagram.
The mesh backing was a gamble that paid off: I stretched fine black mesh across a wooden frame, fixed the segments with tiny cable ties, and the sign has a depth flat acrylic never gives. It cost about twenty-four euros, and the ties let me replace one segment if it fails, impossible on a glued sign. It is not the cosiest sign in my flat, but it looks the most deliberate, and suits a workspace better than anything pastel.
6. Peek-a-Boo Window Cat Contour
The peek-a-boo cat is a cat’s head and two front paws peeking over a horizontal line, as if over a windowsill, mounted right beside my actual window, which makes the joke land. I bent the head and ears from one length of warm-white flex, the paws from a second shorter length, and fixed both to a clear panel so the wall colour shows through and the cat seems to float. The horizontal line is a simple straight flex strip, and the whole sign cost about twenty euros.
Placement is everything here: hung in the middle of a blank wall it reads as a random shape, while beside the window it instantly makes sense. I held it up in six spots before drilling anything, and the spot next to the window frame won by a mile. The panel hangs on two picture hooks for easy cleaning, and Mimi has twice sat on the windowsill staring at her glowing double, the best review any of my signs has received.
7. Retro Neon Gamer Cat Ear Headset Sign
The gamer headset sign is the loudest piece in my flat: a headset shape with cat ears, bent from purple flex with a cyan accent stripe, above the desk where I play games with my brother on Fridays. I drew the headset as one continuous outline, ears included, and bent it from one three-metre length of flex, which took patience: one continuous bend means any late mistake ruins the whole piece. The cyan stripe is a separate short segment glued along the headband; the sign cost about twenty-nine euros.
I almost gave up halfway through, because the ear cups kept coming out uneven, and I only saved it by making a cardboard template first and checking every curve against it before gluing. That template step is now part of every sign I make, and improved my results most. The sign runs on a USB plug behind the desk, switching on with my monitor’s power strip, and my brother insists it is the best thing in the room.
8. The Floating Neon Fishbone & Paw Duo
The fishbone and paw duo is two small shapes on one backing board, a fish skeleton and a paw print floating side by side, and it works because the shapes balance each other, one long and horizontal, one round and compact. I bent the fishbone from warm-white flex, the paw from pink, and mounted both on a dark-stained board about fifty centimetres wide, leaving generous space around each shape so neither crowds the other. The board hangs in my kitchen doorway, and the pair cost about twenty-five euros in total.
Wiring two shapes on one board is simpler than it looks: both flex lengths meet at one junction box on the back, and one USB cable powers the pair, so one plug and one dimmer. I spaced them twenty centimetres apart after trying them closer first, because at ten centimetres apart they blurred into one blob from across the room. The fishbone was Mimi’s favourite shape to watch being made, though she mostly wanted to bat at the flex.
9. Soft Cloud & Peeking Feline Horizon
The cloud and peeking feline is the gentlest sign I made, a soft cloud outline in warm white with a small cat face peeking from behind one edge in pink, hanging in my bedroom corner where evening light falls softly. I bent the cloud as one wobbly, looping line, deliberately uneven, because a perfect cloud looks wrong, then added the cat face as a separate piece, two ears and a curved cheek, tucked against the cloud’s edge. The sign cost about twenty-three euros and took one relaxed evening.
The uneven cloud line matters: my first attempt was too regular and looked like a cartoon weather symbol rather than a cloud, and loosening my hand fixed it immediately. I use the dimmer on this sign most, because at full brightness the cloud glares, while at half brightness it glows like dusk light, exactly the mood I wanted. It is the sign I would make again first if I ever moved: simple, forgiving, and hard to get wrong.
10. Customizable Neon Frame Box for Photo Display
The frame box is the most useful sign I made, a rectangular neon frame, about forty by fifty centimetres, with small clips inside for swapping photographs, so the glow frames whatever pictures I choose. I bent the rectangle from warm-white flex on a clear sheet, fixed four tiny brass clips inside, and hung it in my hallway, where it holds three prints of Mimi and one of my grandmother’s garden. The frame cost about twenty-seven euros, and changing photos takes under a minute.
The clips were the detail I got wrong twice: my first set was too weak and the photos slipped, and my second set scratched the prints, before I settled on small brass clips lined with felt. The frame runs on a USB plug with a dimmer, and because the photos sit inside the glow, the piece looks like a little gallery at night. If you make only one sign from this list and you love photographs, make this one, because it changes with your pictures.
My desk wall now glows softly every evening, and the whole collection cost less than a single shop-bought sign. Pick the simplest shape first, get comfortable bending the flex, and the cursive script will feel easy by the time you reach it.
