Should drawer pulls be centered?
Pulls should be placed horizontally on drawers. For small drawers (less than 24'' wide) center the knobs or pulls in both directions. Just like on larger drawers, pulls should be placed horizontally. Knobs and pulls can also be placed centered at the very top of the drawer panel, where the drawer rail begins.
Where should Handles go on drawers?
