I like incorporating natural materials into my art, and I have collected some gum nuts of two types, and some small pine cones from Casuarina (Silky Oak). My plan is to drill holes and hang them from ?something? Before drilling I decided to paint them with gouache - I find that things painted with acrylic paint tend to stick to each other.
These will decorate a largish item; the smaller gum nuts could possibly embellish a journal but the large pine cone, although only about the size of a thumbnail, would be too heavy for small or light artworks. And they are not flat enough to use inside a journal or book.
