Product description

Product Description What is Westfoam?Westfoam is a UK manufactured, strong and lightweight material that is easily cut with a sharp craft knife or picture framing mat cutter. Westfoam is made from acid-free paper, is pH neutral, and has been anti UV treated to resist yellowing, is non-toxic, produced without CFCs, does not attack the ozone layer and is made with recyclable polystyrene for a more sustainable future. What are Westfoams uses? Westfoam is commonly used for the mounting of prints and photographs or as backing in picture frames. Westfoam can be easily formed into shapes that can be used for interior design and architectural models and for the construction of model aircraft and drone chassis’ where a lightweight, strong and sturdy material that is paintable is required. Westfoam is also the choice material for photographers looking to improve their lighting setups. Prototypes & MockupsPresent your work professionally and command greater attention with Westfoam. It can be cut easily with a craft knife to give the sharpest of detail to any construction, from a product prototype to a scale model of an entire city. Being so light in weight Westfoam is very easy to transport and can be enhanced and coloured with acrylic paints, Indian inks, marker pens and spray paint. PresentationsWestfoam creates an ideal backdrop for your presentations and story boards because it is light, durable and easy to handle. Present your work professionally and receive greater attention for your presentations, artwork and plans. PhotographyThe inexpensive and extremely versatile Westfoam is a must have tool for any photographer. It can be used in a variety of shooting scenarios, and compared to professional solutions is a very cheap alternative. Create cookies (Cucoloris), where you cut shapes out of the Westfoam, then shine your lights through the shapes at the subject to create interesting light patterns as a background for your subject, or just use an A1 sheet as the main background for your subject. Westfoam can also be used as a fill light source, which will reflect the light source back on the scene, in return filling in any excess shadows on the subject while not having to adjust the contrast. Another good use in photography is as a light bounce source. Mount a white sheet of Westfoam above the subject. Now bounce your lights straight at the Westfoam which will “bounce” back onto the subject as a soft or “diffused” light. Hobbies & CraftWestfoam is perfect for all manner of craft projects; stick with sequins and pearls, incrust with cloth, paper and cover with brilliant coloured serviettes and more. Your finished surface and project can then be coloured and designed. Westfoam provides a great template and base for papier mache and plaster of paris. MountingWhether mounting photographs, charts, layouts or floor plans, Westfoam will do the job with impact. Creating a collage with foamboard is easy and fun with Westfoam, using a simple craft glue or docrafts Stick It you can stick on photos, fabric and a range of materials to put on show and liven up any room.

I wrote to Bigamart's customer support and they accompanied the process of reshipping the item until it finally arrived. I felt a genuine effort to solve the problem till it was finally solved.

The package was here in Australia from England in a few days — so quick! Something was missing and they refunded it straight away. Pretty happy with these guys.
