This is a nice project for a kid's room or a game room and it can be made for a few bucks. It can be made easily for your changing tastes.

Step 1: Materials

Round Push Lamp (Dollar Tree)
Translucent plastic placemat (see 2nd pic for sample)
Clear packing tape
Glue

Optional
Pencil
Rubberband

Step 2: Creating the Lampshade

Wrap placemat around push light to create the lampshade.This will help you locate where the ends will meet. You can secure it with a rubberband at the bottom to help secure it as you work. You can mark it with a pencil if needed. Tape the inside seam with clear tape and dot the outside seam with glue, if there is overlap. Use a piece of clear tape to secure it until dry.

Step 3: Securing Lampshade to Push Lamp.

Dot glue around the push lamp, smear if preferred. Place lampshade on push lamp which should fit snugly. Let dry. You can remove exterior tape after glue has dried. You can trim down inside tape also, so it is not visible.
