Mottled parchment papers are widely used to make lamp shades. If your lamp shade is damaged, you can create your own one.
For the first shade covering, you need to choose a simple cone shaped lampshade frame with a smaller circle-shaped ring with ribs extending to an even smaller washer-like circle. This frame is quite common and is called a spider frame.

Use scissors to cut out parchment shade. Dry fit the parchment to the frame. Make any small trims. Use bull clamps to clamp the parchment to the frame at the top and bottom. Position the seam over a side rib. Place the parchment on the top, bottom and side frames.
Lift the edge of the paper where it overlaps. At the top and bottom papers, apply a head of hot glue. Press the paper together to form a tight, strong seam. Run the hot glue between the clamps and glue the parchment to the top and bottom frame. Let the glue dry. Remove the clamps and apply hot glue where the clamps used to be.
Along the top outside edge of the shade, apply paper edging tape. Make sure that there should be half of the tape on the outside of the shade. Pull the tape over to the inside of the frame and then make small V-shaped cuts along the tape. Cut around the spider frames, and carefully fit tape. Stop and start at your overlap seam.
