Flexagon templates: trihexaflexagon, hexahexaflexagon, tetraflexagon

A flexagon is a folded paper strip that opens and flexes to show faces hidden inside. These nine pictures give three kinds: a trihexaflexagon of ten triangles coloured by face, a hexahexaflexagon of nineteen numbered triangles, and a tetraflexagon of squares with two cut-out windows. Each comes as colour faces, numbered line art and felt-tip. Type a variation, such as pastel faces or a longer strip, and the fold layout stays the same.

Frequently asked questions

What do the nine pictures show?

Printable flexagon strips in three kinds, each in colour faces, numbered line art and felt-tip styles.

How do I close the strip?

Fold along the dashed lines and glue the tab marked on the strip. Then flex the strip to reveal the faces.

What is the difference between the three kinds?

The trihexaflexagon is a strip of ten triangles, the hexahexaflexagon a strip of nineteen, and the tetraflexagon a grid of squares.

Can I ask for another variation?

Yes, type a variation such as pattern faces. That is a request, and the strip may not match the sample.

About toile

This page is a showcase and a starting point: nine samples already rendered, three readings of the pack crossed with three styles, each shown at the size and ratio it was made for. Take any of them further on the wall with a few words, or ask for all nine again under your own direction; a sign-in keeps what you make, and it is free while Toile is new. The recipe behind each sample — the subject, the style, the palette, the framing — travels with the image rather than staying private to the render: it is in the alt text of every sample and in the page's own structured data, so a search engine reads the same handles a person would.
