What is the best product to use and best way to match the texture of this unique interior render?

[alagogold]

I am working on renovating a 1930's home that has a double brick exterior and single brick interior walls throughout the front half of the house.  There are both interior and exterior render points that need to be patched (but I'm starting with the interior seen here) after we've had reclaimed timber windows installed (improved with double glazing) replacing some aluminium frames that were put in the 1960s/70s, brining some of the original character back to the home.  

I have more of a 'flat" render' that I'm less concerned with given the previous posts here on how to fill in render on brick walls.  However, with the unique render style (no idea what it's called) throughout most of the house I need to know how to re-create this pattern or design.  Thank you tremendously for your advice. Advice to match texture that is blue
