Although not clear, we use five foot long foundation forms from Lowe's. They are cardboard but last a long time. Most of my hobs are over four pounds with one topping the scales at five & a half. (The forms are only about $6.50 and come in two different sizes). Hope it helps, melissa m. nelson, CPC The Full Nelson Ferretry The Ferretry in the Country [Posted in FML 7618]
