I have seen some classes including from Judith M. using a special kind of foam for making hat blocks. Does anyone know where to buy the right kind of foam for this type of project? When I search online I get a little confused between foam used by builders as insulation and foam for model making by architechts (which is pricier)- but maybe even smoother and easier to work with? If anyone has experience sourcing or working with either type, I would appreciate the information.Thanks!Corina HaywoodSee More
