What you need:

1.) Brush
2.) Liquid glue
3.)  Different patterned lace doilies
4.) A balloon
5.) An energy saving lamp

Step 1: Blow up the balloon to the size you want the final lamp.

Step 2: Thin out the glue with a bit of water before using the paint brush to apply all over your pieces of lace.

Step 3: Stick the lace doilies onto the balloon, overlapping them piece by piece. Leave a round space on top so you can insert the bulb.
