G'day everyone, for my dio that i am currently working on (working on the figs actually) i want to have a stone barn/shed, it has to be 1:35 scale, problem is i have no idea how to go about making one, i thought about making the wall out of plaster then carving the stone shapes into it, or making a mold out of rubber and pressing little pebbles into it, to make a mold to pour plaster into it, but they all seem like they would take sooo long, i want a quick, simple way to make stone walls, anyone who knows how to do this should have it made into a feature, as im sure it would be very helpful to others

thanks in advance, cheers
