This is an fascinating linear design of rhombus and triangle twists.

Because it was famous within the title, this design is by Madonna Yoder (who is named gatheringfolds on-line). 

It is a mirror symmetry tessellation. Because of this the back and front are mirror photos of one another. Understanding this earlier than you start fixing a tessellation could be useful in discovering the answer.

The entrance of the design is rhombus twist and open again triangle twists. 

The opposite aspect is identical reversed. 

This level is additional illustrated by evaluating the primary picture and the second picture (the entrance and the again respectively). 

It is an intermediate degree fold that you are able to do with out an excessive amount of fuss. 

My crease sample sketch is included on the finish.
