I recently was given a partial pallet of travertine stone. In total there is 5 different sizes of stones. I can't do the standard paver patterns because I don't have enough of each size. Is there an easy way to figure out what size/shape patio I can do with what I do have. I was looking for a collage program that I could feed in the sizes and quantities of the pavers to and "shake" into a shape. Does anyone know of such a thing. The only ones I've found so far you pick a shape first.
