Vellum is a type of paper made from cotton and wood pulp, which can be used for making greeting cards or scrapbooking, as well as for tracing designs. Although Vellum is not completely opaque, it's not completely translucent either but it still has a slight translucent property allowing you to see through it. Acetate is clear plastic and completely see-through. Both are perfect for layering, using as overlays, or tracking designs. Our selection of vellums and acetates are all acid and lignin-free and made from high quality materials for papercrafters.
