Woodworking projects generally require, well, wood.  You can get dimensioned lumber and plywood from Home Depot, Lowes, Tart, TW Perry, etc.  Dimensioned lumber being 2x4s, 2x10s, etc.  Rough lumber is where you'll find more variety of types like maple, cherry, oak, etc.  Rough lumber is sold in 4ths, so a 2/4 thick piece of lumber will actually be 1/2 (as opposed to dimensioned lumber, which is usually 1/2 inch smaller than the stated size).  Rough lumber is sold by the board foot.
