Onto the next project ... adding a countertop with a sink and shelves in the shed.  Custom sizing the shelves underneath for all the soil, fertilizer and other shed residents that were always half-hazardly stacked in piles on the floor and often tripped over. The 16" wide heavy-duty shelves to the left of the window I installed last summer.  The countertop will rest in the area I cleared out along the darker pressured treated plywood frame that was used as a foundation for the outside river rock that I installed halfway up. The drain pipe and water line for the sink, I installed when I was pouring the shed foundation 5 years ago.  They are under the window and to the right a bit.  I always plan way ahead for things, knowing I someday wanted a sink in here for watering starter plants and washing hands.  Eventually I get around to implementing those plans and  completing the project.
