This was my first project and I learned a lot about drilling and sawing. I love the cute kitchens people have built with this plan, but we went for realistic with neutral colors since it is going to be in our own kitchen and not in a playroom. The biggest challenge was was that I was continually finding components I wanted to add, but then I would have to redo things I'd already done to fit them in.
For someone doing this plan, my only suggestion is to put the pocket holes inside the oven area instead of inside the sink area, as the countertop is easier to screw in that way.
For the fridge, I used 11x14 clear acrylic for the shelf and glued in a motion sensing light. For the farm sink, I used glidden super glossy white paint, which is supposed to not show brush strokes but it did for me. I also made the shelf under the sink a half shelf. For the oven, I used cookie racks from the dollar store and a push-on light inside. The counter top is a realistic looking laminate I found in the shelving dept of Menards for $2. I found the wire disks for the stove top at a surplus supply shop for 75c each. My husband tiled the backsplash and we added that board after the grout had dried so the rest of the kitchen wouldn't get grout on it.
