We have installed most of our cabinets, and hit a possible snag in our plans. We have drawer vases (15x15 deep and a 30x15 deep) as part of our peninsula. I desperately want to put interior (hidden) drawers inside of the top drawers on each cabinet (one for junk/pens/etc, and the other for towels and pot holders). The maximara low drawer only comes in a 14 3/4” depth, and this will not allow an inset drawer. Blum makes a 12” drawer slide, which I think would work fine. But I have no idea how to accomplish this task. Please advise.
