Started on the shelving unit I bought wood for oh, maybe 6 months ago

Well I finally got around to starting on the shelving unit I want to make for the basement. I bought the wood in 2 stages so far. I will need more if I decide to make another unit. I had a friend over to cut a few pieces for him and had him help me cut the 2 3/4 sheets of plywood with me. It is a bit much to cut a full sheet by myself. I can cut a 1/2 sheet on my own but 3/4 is just a bit heavy and also hard to cut on my own. So I have both sheets cut length wise and will work on getting all pieces set and ready for assembly maybe this week. We don’t really have any plans for the 4th so I may work on it a few hours on the 4th.
