Tape stencils to the resin chair. You can stencil words, party designs or abstract patterns.
Place the chair on a tarp. Color in the stencils with a spray paint designed for plastics.
Remove the stencils and allow the paint to dry.
Add stickers to the chair. You can use name stickers, band decals and anything else with an adhesive backing. This will give the chair a funky, patchwork kind of look.
Fashion ribbons and bows from streamers and tie them on to the chair. If you are having a party, attach helium balloons to it.
