You have a roll of 2-1/2" strips
A Moda JellyRoll of Morris Earthly Paradise:
Cut the strips into parallelograms
by cutting them with a 60 degree ruler every 7-1/2".
Flip half of them.
Combine them with a Jelly Roll of Moda Bella Solids, say Snow White.
Junior Jelly Roll of Snow
Cut them the same way
Alternate till you run out of fabric.

I do not believe I have ever noticed this pattern before.
At first I thought it was a braid design.

It's sort of like a braid but the angles have to be 60 degrees---not 90 degrees.
A tessellation---and perfect for JellyRolls.
UPDATE: Astute commenters noted how hard this would be to sew---it's all set-in seams, which
is probably why the pattern is rarely seen. How could it be modified to make it possible to do it with straight seam on a machine?
Well you could make it all diamonds.
Or some diamonds.
But I think it was a hand-sewing project.
