i am going to be using wood today to make my shelves. not too many, its only a 6x12. i am going to use 2x3 studs. do you think if if i put the studs spaced right, i could get away with a thin plywood? my shelves are basically for holding smaller supplies, like spools of trimmer line, bags, loppers, hand trimmers, oils, etc. maybe (2) echo trimmers on the top shelf. any suggestions, i am looking to make it light and sturdy. i will post a before and after... here is the before.
