Buying ? Online? Local? in Materials, prototyping and manufacturing Posted February 4, 2012 · Report reply Hi guys, I'm wondering if you guys have recommendations for buying things like modeling/prototyping foam. My friend who does id suggested foam they use in flower decorations? I'm just not sure where I can go buy this stuff. I would like to start with MDF and modeling foam (I already have some sculpting clay to play around with). Thanks a lot.
