Since I have little real world remodeling experience I like to run my "concepts" by someone else!
The kitchen (1929 house, not level floor) is getting redone with euro style cabinets I'll be making, those will just be simple boxes. Here is what I was thinking of for the toe kick.
The toe kick will be a 3/4" plywood (perhaps OSB since it's flat and I have it, but I have some mixed grade 3/4" regular plywood) platform with some screw legs (perhaps from IKEA) to level it. I'll have some furring strips attached to the edge. I can then take the material (probably fir 1 x 4 or 1/2" plywood) I'll use for the face of the toe kick and set it on the floor and scribe a line to cut off the top.
Does this sound reasonable? Not all my ideas are!
