We investigate experimentally and numerically the evolution of dense suspension drops that collide against a smooth solid surface and flatten into a rapidly expanding monolayer. This creates a lace-like pattern of particle clusters separated by particle-free regions. Both the expansion dynamics and the development of the spatial inhomogeneity is shown to be captured quantitatively by simple models derived from balancing forces acting on individual particles.
