Yes, it's true....this texture sheet is molded from crumpled aluminum foil. A carefully manipulated and stabilized piece of foil, but still Aluminum Foil.
Yes, you could just wad up foil and press it
into something, but that's an impression, an inny, this is a mold of the actual thing, you get an outty.
Look at these pictures, it is a great texture sheet, and versatile also.
This ivory polymer clay with a Burnt Umber patina. Looks good, doesn't it. It looks more like leather or paper, very organic, very nice.
