I also bought the Sauder sewing cart through Walmart. I am in the process of putting it together, but can't find my Philips screw driver. The directions are very thorough and clear. Before starting, I separated all the nails, screws, etc into individual baggies (snack size) and it helped make sure I had the right count of each item according to the instructions. The extension top clearly states it is not for cutting use, probably because it only is attached to the cart with hinges and not sturdy enough.
