Thank you for the great compliment! These pulls and knobs can be found at Amerock. These are the rubbed oil bronze finish.
When placing hardware on "wide" drawers - make sure the hardware does not get "lost" If you are not using handles or cup pulls and opt for knobs then you may want to consider using 2 on each drawer. The drawback to that is you now need to use both hands to open the drawer so you don't rack the drawer over time. .
In this instance we used a fairly plain cup pull for this project. Also we used a contrasting hardware so it stands out more especially where we used fairly small knobs on the doors. It is hard to get it wrong when you are doing this unless you are incorporating different styles and finishes or using hardware that is scaled wrong for the size of the doors and drawer fronts.
I hope this helps!

Completely agree with iamthegardner; gorgeous kitchen! Could you expound a bit more on your statement above, "or using hardware that is scaled wrong for the size of the doors and drawer fronts"? Do you have a quick and easy base formula for calculating the appropriate size pulls? For example, "1 inch of pull for every x inches in drawer/door width." Thanks again for being so generous with your advice!
