Mix-Up Clay is a super soft and light air drying clay unlike any other modelling material. Inside the pack you'll find a large clump of white Mix-Up Clay plus four coloured dyes. Mix the dyes into the clay using your hands - add more than one to mix up different colours! The dye doesn't stain your hands and is easy to knead into the clay - very satisfying!Tear pieces off the main clump and make separate pieces in different colours. Then mould them to create models, beads, brooches, pencil toppers....whatever you'd like! After around 6 hours the clay will dry and harden. Keep the clay in the re-sealable bag to prevent it from drying out between uses.
