Give a set of draws a quick update.

Before 

 After.

On my last trip to IKEA, I bought a pack of six SÄTTA handles in black simply because they were so cheap, £2.50 of six handles can't be bad!  And as luck would have it, they were a perfect fit for a couple of sets of drawers in my office/spare room,  I didn't really like the silver handles much before and the black ones made for the perfect update.
