Twigs ,small branches : can be boiled in hot water ! to bend into shapes such as: jewellery , miniature ornaments, homemade beads as wood bends in hot water . Easy to craft with and free also. Make sure to wash them first when found and collect cuttings of twigs from garden waste , they can be crafted into small macrame styles,
Clay: can be dug up from the ground, not the surface layer which is mud with other natural sediment, clay is quite orange in colour and very wet when found below the mud. Will mould into hands naturally.
Just a small list of fun nature things to do … Random
