This is great. This should be a sticky. I do have a question though if you would since you seem to know more about wood products.
On this home depot page, which sheet of 4x8 would you say is the absolute lowest quality I could go and be ok. I am on a very tight budget and I don't care about looks that much as I do about price and function. I will be building about 7 of these.
Also how did you break down a 4x8 sheet?
