I have a large refacing project to do in my workshop. I am going to reface the cabinets and bring them into the 21st century. I have learned that the hardware is the most expensive even if i buy my hinges from a place like wwhardware.com I stopped by my local Habitat Restore today and they have bags of 6 for $2 each... the problem is i dont see a number on them like i have on some other hinges. it there a way to determine if its a 1/2, 3/4, full overlay hinge etc.
