Once your Ivar cabinet is assembled it will look something like below. You can paint the wood before you put the unit together, but as I wanted to keep the inside natural, I painted the frame once it was all together, and did the doors and shelves separately before attaching them.
This was really fun to do. I taped off the wooden section of the legs whilst I sprayed the tops and bottoms gold. Once they were all dry I stained them to achieve a maple wood finish which really bought the unit together. You can switch out the legs pretty easy, simply unscrew the old, and replace with the new!
