No problem at all - it is actually not very difficult - I started from one repeating element made with splines and sweep modifier and then distribute it onto larger plane still in 2D space into bigger element depending on the size and then what was really new to me but it is really cool technique to use patch deform modifier - it lets you deform any kind of shape or pattern, whether you want to bend it or whatever .. because you actually edit only the patch while not deforming your original shape :)
