The approximate size of the box is 36 " across the front, 10-12 " high and Deep.
I have the cupboard handles = they will also need mounting too.
But do not know how to select the hinges. I've already been to Home Depot and am overwhelmed at the number of hinge selections
I will reimburse you for the cost of the hinges.
I have the wood for the 2 door - it will need to be cut to fit the front opening in the box.
When the box is completed it will to into my kitchen and be part of my cupboard storage system.
I can send pictures of the box and the place in the Kitchen where the box will go - to save a trip to see the project.
I can also drop the box off to you.
