Using your glass ornament is easy! Just use the included rope to hang it up wherever you like, such as on your Christmas tree or around your home. When customizing, make sure to follow the rules - use standard English and check your spelling. This will ensure your personalized ornament looks its best. As for maintenance, gently wipe the glass with a soft, dry cloth to keep it clean. Avoid using harsh chemicals or abrasive materials, as they could damage the glass or the printed design. Also, handle it with care since it's made of glass and can break if dropped.
