Diamonds - colors on grey

A story from last week
I have the task to design a small patched surface not so difficult to be sewn even from beginner.
So I played with grey and color squares  some days ago.
The result is quite good.

I used the ripper once when have not exactly points.
And this have put another idea in my mind.
What if...
using wonky triangles
using different colors
these colors are from red palette only



I have to made it.

The red one

The blue one

The yellow one

The green one

I would take a pictures for the next one to blog a tutorial.
