Cardboard triangle with rounded corners and hole – 3–50 cm

The birthday is just around the corner. The craft supplies are on the table. And you still need a shape you can paint, write on and hang from a string. That is exactly what this cardboard triangle with rounded corners and one hole is for. It is sturdy bookbinding board, and the hanging hole is already cut cleanly. It is made for your next craft session. Sizes range from a small 3 cm tag to a large 50 cm wide decoration.

What changes for you

• You thread ribbon or string straight through. The hole is already laser-cut, so there is no punching or drilling.
• Your garland for a wedding, birthday or party hangs straight and lasts the whole celebration. That is thanks to 1.2 mm solid board at 755 g/m². It does not warp like thin card.
• You design it however you like. The smooth, untreated surface can be glued, painted, coated or varnished.
• You can craft with a clear conscience. The board is made from 100 % recycled material.
• You get exactly the size your project needs. Choose from 3 to 50 cm in 1 cm steps.

Why this cardboard triangle makes a difference day to day

Cardboard shapes you cut yourself often end up lopsided. The edges fray, and the hole is never where it should be. With a ready laser-cut cutout, you go straight to the fun part: designing, writing and hanging. Your bunting, name sign or gift tag looks neat and consistent. That works on the dining table at an engagement or on the photo wall at a party.

Material & finish

The triangle is made of solid bookbinding board. It is the same material that keeps book covers stiff. The surface is smooth and reliably takes paint, glue and varnish. The rounded corners make the shape comfortable to hold and give it soft outlines. The brown edges come from the laser cutting and are typical of this cutout. Every triangle is made in our own production in Pößneck, Thuringia. The finish is clean, and you can rely on it with every piece.

How to use the cardboard triangle

• For birthdays: thread several triangles onto a string and write names or wishes on them. The bunting above the table sets the mood before the first guests ring the bell.
• For weddings or engagements: each triangle becomes a place card or a tag for a money gift. Decorate it with care and attach it with a ribbon through the hole.
• For Valentine's Day: a small triangle on a gift, written by hand. A gesture that is remembered.
• Crafting with children: the rounded corners and sturdy board cope with impatient hands. And the result can go straight in the window.
• In a café, shop or at a market stall: write on the triangles as price tags or signs and hang them at the counter. They look uniform, are quick to swap and are made of sturdy board instead of loose slips of paper.

Good to know about bookbinding board

Bookbinding board is the classic material for book covers. It was developed to keep its shape for years and to hold paper or fabric coverings reliably. This helps you when crafting. The triangle stays flat even when covered, painted or varnished, and it does not sag.

Care & durability

There is not much you need to do. Store the cutouts somewhere dry and keep them away from constant moisture, because the board is untreated. This keeps the surface smooth and your decorations looking good for a long time. You can reuse finished pieces from one celebration to the next.

Frequently asked questions

Can I paint the triangle or glue things onto it? Yes. The smooth, untreated surface of the solid board can be glued, coated, painted or varnished.

What is the hole for? Pull string, ribbon or wire through the laser-cut hole. Use it to hang single triangles or to thread a whole garland.

Why are the edges brown? The triangles are laser-cut, and this creates the typical brown edges. This is not a defect. It is a feature of the production process.

Is the cardboard environmentally friendly? The bookbinding board is made from 100% recycled material and is produced in Thuringia.

Can I use the triangle outdoors? The board is untreated and should be protected from constant moisture. It works well in sheltered spots, such as under a roof or a gazebo.

This is more than a piece of cardboard. It is about the moment your own garland hangs above the table and the party feels like yours as soon as people walk in. Just choose your size and quantity, and get started.
