These michaelmas daisies are actually positioned and oriented extremely precisely (on the edge-centres, vertices and some of the face-centres of the semi-regular square and triangle grid S43433) rather than being scattered randomly. However, the complex symmetries of that plane group (having tetrad rotational axes but with its mirror axes along the bias diagonals while the glide axes correspond to warp and weft directions) result in the continual breaking up of the easy patterns that the brain wants to track (and it's even harder when all the flowers are made the same colour). This puts it on the borderline of being a "ditsy" pattern. Meanwhile, the tetrads ensure that the design isn't favouring any particular fabric direction over any other.
Currently displaying a version in natural michaelmas daisy colours on a green background. Other colours, sizes and orientations are available on request and you can even ask for a combination of several designs together.
