Unused drawers could easily convert into a jewellery drawer by lining it with scented drawer paper and then you could put in large deep seashells, crystal coasters or ashtrays and miniature decorative boxes to place your jewellery in.
Many jewellery stores sell soft cloth drawstring pouches for individual pieces of jewellery. You can also find small plastic mini zip-loc bags in which you can store jewellery—available in craft/dollar stores. By storing jewellery in individual bags, it will prevent your jewellery from getting scratched or rubbing against each other.
Other items that you can find within your household include tie rack hooks and key holders for chains, watches, rings and bracelets. A mug holder that has branches can have rings slipped on them.
