Resin casting opens up a whole new world of art and craft possibilities. You can use resin alone or in combination with other materials like paper, fibreglass mat and even fresh flowers to make sculptures and jewellery. Polyester resin is often called clear casting resin, but it doesn't have to remain clear. You can buy colourants especially formulated to mix with clear casting resin, but it can be expensive and difficult to find. Acrylic paint offers an inexpensive, readily available alternative.

    Pour the casting resin into a clear plastic cup.

    Stir for 15 seconds to mix the paint into the resin.

    Pour the resin into your mould as you normally would.

Tips and warnings
