Smoothfoam polystyrene foam blocks are great for all sorts of crafting projects. Our craft foam blocks and foam cubes are hot wire cut out of High Density EPS. They are a perfect base for custom bookends, or even some custom home decor projects. They cut like butter using a hot wire to create spectacular wood like cut outs at a fraction of the cost. And unlike Styrofoam® cubes, Smoothfoam does not crumble leaving a dusty mess. Like all Smoothfoam items they are durable and easy to glue as well. Find a smooth block of foam below.
