For the most part, you will hang small items (pictures, etc.) the same way you do upstairs. You can use the 3M hooks that stick to the walls, nails, screws, etc. For larger items like televisions, heavy artwork, or large frames with glass, please use the anchors seen in this link. For those, you will pre-drill a ¼” hole, and use a handheld screwdriver to insert the anchor and also the screw.
