Use self-striping yarn to create these cute little decorations in a range of shades of green.

Each tree is made of three bell-like sections (a bottom, middle and top) which are worked flat, then seamed. The three parts are then stacked to create the tree shape and held together with a ribbon loop, with a star bead to decorate on top. To complete, sew on beads as tiny baubles. You can mix and match colours, or break your cake into sections of each colour and make trees all in one colour.
