Sleeping pad foam by the foot
I found a site earlier this year that sold closed cell foam for sleeping pads of the roll so you could order custom sized pieces, I have forgotten the site however, does anyone know what im talking about?
I just ordered one from jacks r better.
light, tough, fine grained common blue foam in a lot of pads. It has many other uses including floor underlayment as a sound barrier and packaging as a buffer. You may find a local packaging or flooring company has it.
