- Step 1: Choose a Pattern and Print It
Choose a tri-tetraflexagon to make. Download and print the pattern.
Choose a design that prints in color, or select
one of the black & white
patterns and use your creativity to add color and designs. It is
easiest to fold patterns that have numbers or counting dots. Make one
of these flexagons first before trying any of the others. To aid in
folding and decorating the blank and unnumbered patterns, guides that number the
faces are included on the patterns. The Labeled Guide
pattern can be used to make your own flexagon creation from designed
paper or picture cutouts—see the sidebar for more details.
Patterns are Adobe PDF files. The
Adobe Reader is available for free.
All of Aunt Annie's project patterns are designed to be printed on standard letter-size paper (8.5"x11" or A4).
When printing from Adobe Reader, you may need to select Auto-Rotate and Center or Choose paper source by PDF page size to ensure the best fit.
- Step 2: Color and Decorate Pattern (optional)
Color the pattern template as you like with markers, colored pencils or
crayons. You don't need to color the glue tabs marked with '*'. The
Frames patterns are particularly suited to rubber
Tip: On blank patterns, follow the Coloring
Guide. All of the squares that make up a flexagon face have the
same number, so color and decorate them with that in mind.
- Step 3: Cut
Cut around the pattern piece on the outline. Try to make the cuts
very straight and accurate. The cutout pattern has
14 squares that, when doubled over and glued, result in seven
- Step 4: Double Over and Glue
Make a two-sided pattern with a double thickness by folding
the pattern piece in half lengthwise and gluing. To make a sharp,
straight fold, first score on the fold line.
To score: Use a ruler and the empty ballpoint pen (or bone folder) to make an
indent along the fold lines.
- Step 5: Fold
Score and fold back and forth on all the solid lines. Do this for each of the
seven squares of the
tri-tetraflexagon. Follow the folding instructions very carefully.
glued pattern as pictured, with the 3-3-1
sequence up and to your left.
Fold the leftmost square over the adjacent square on the line between the
two squares numbered with a 3.
squares with 3's are now on the inside of the fold, and the glue tab,
*, is on top.
Fold back the three rightmost squares on the line between the
squares numbered with 1 and 2.
squares with the number 2 are now on the back, and the front side
has three squares with 1s and a glue tab, *.
Pull forward the square marked with a 1 from behind the glue tab.
there are four squares of the same color, numbered 1, on the front,
and four squares numbered 2 on the back.
last step is to glue the flexagon. The two glue tabs marked with *
are now face-to-face. Glue them together.
Wait for the glue to dry before flexing your flexagon.
- Step 6: Flex
With the side of the flexagon numbered 1 facing up, fold the flexagon
in half vertically with the squares numbered 2 on the inside of the
fold. Gently part the flexagon along the fold line to reveal the
number 3 side. Now the number 2 side is hidden.
To see the number 2 side again, flip the flexagon over so the
number 1 side is up, and repeat the flexing process. The
tri-tetraflexagon is very simple, and has just two combinations of
its three faces—sides 1 & 2 and sides 1 & 3. There is no way
to get the combination 2 & 3.
