Kind of embarrassed to share a picture of mine, or even this picture of half of it. But, in this final week of campaign, I will endevour to deliver the truth, the whole truth, and nothing but the truth:
The base is part of an old kitchen I replaced in our first house, and I moved to our current house when we moved 30 years ago. The surface (under the cardboard) is just a scrap piece of 3/4" plywood. Above the pegboard is a set of the hanging cabinets from the same kitchen. In case it isn't obvious, I do not clean up my bench when I finish a project, I clear space for new projects as necessary.
