Some of the best IKEA hacks come from simply reusing an existing item, no drilling required. That's certainly the case with this simple idea: using the iconic Plastis ice cube trays, plus the $9.99 Inreda DVD rack, as a jewellery holder.
We featured a similar idea recently using a candlestick holder and plate combination, but this approach (outlined, unsurprisingly, by our frequently-referred-to friends at IKEA Hacker) has the advantage of letting you sort individual items easily. While that would work equally well with any ice-cube tray, the $0.99 price tag might be hard to beat.
