Can you post a picture of the handles you are using?

we have a larger one for the pantry cabinets

also, regarding the second photo, should we put 2 handles on the larger drawers?

Center the handle in the middle of the drawer unless you want to put them at the top. You might go up to the photos tab, and go through pictures of that style of cabinets to see how others have handled this. As far as putting two on a larger drawer, if you think they need it, do so, if not, don't.

Another consideration to take into account : The width of drawers, e.g. if storing heavy objects in drawers and the width is wide than handles on both sides of drawer may be needed (knobs is another option). But your drawers look like 2 feet or less, so yes, center them
