Smoothfoam crafting foam sheets are great for all sorts of crafting projects. Our polystyrene foam sheets are hot wire cut out of High Density EPS. They are a perfect base for that picture board, 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®, Smoothfoam polystyrene sheets do not crumble, leaving a dusty mess. Like all Smoothfoam items they are durable and easy to glue as well.
