DIY Elephant hanging cutouts- or any silhouette can work. Find a stencil online and trace it onto different colored scrapbook paper. Then tape, glue, or staple onto a string. I love the elephant idea :)
Flower paintings by tracing and creating raised drawing, then stamping with paint. Making custom stamps without carving (plexiglass and silicone) - and as a bonus, loading stamp with ombre paint pattern.
