Reticula Challenge #295

The Diva Challenge this week (#295) is the same as the previous week, so to use a grid as base and fill it up with a design of your own.   The challenge is to make a 'Reticula' tile.  I did not participate last week, but I decided to go for it this week and I had some free time this afternoon.  My daughter invited a friend for playing this afternoon, so more free time for me !

For this week's challenge we have to choose a design that is asymmetrical.  Then alternate the design inside the grid - creating another more complex pattern!
