An icosahedron is a 20 sided shape where each side is a triangle. Here is the star version.
Project Info
Paper required: One sheet 8 1/2 inch x 11 inch (or A4)
Finished Project size: 3 1/2 inches (9 cm)
Difficulty Level: Beginner
INSTRUCTIONS
STEP 1
Print the Icosahedron Star pattern onto the paper of your choice.
Read the pattern key included in the General Instructions.
Step 2
Cut out the five pattern pieces by cutting on all black lines.
Step 3
Fold pattern pieces on all red and green lines. Green lines are valley folds and red lines are mountain folds.
