The little paintings you can literally just place wherever you need a splash of colour! They can be added as an accent to an area. Unless you want to keep each artist together then you can have them on the little wooden crates that they came in. I usually display them on different heights so you can see them all.
For driftwood, 2 of the 3 have hangers on the back so they can be hung up on the wall. The third one doesn’t have hardware to hang on the wall so it can be placed on the shelf, or you might be able to find a way to suspend it in the air with a fishing line.
