So lets start!
Step 1: Materials needed
1) White cardboard,
2) Scissor and anti cutter,
4) Ruler (to measure),
5) Super glue and white glue,
6) Lighting system (bulb holder, plug, wire, light bulb),
7) Golden glitter paint and paint brush (if you want to paint the flowers).
Step 2: Getting started
The lampshade I made is arch shaped, 15 inches tall and 7 inches wide. I had to cut out a cardboard piece of 15 X 20 inches and bend 12 inches into an arch shape. Make sure to keep an inch extra while cutting the width because you'll have to glue and join the sides.
Step 3: Designing, cutting and joining
When you're done drawing the flowers, take an anti cutter and carefully cut the sides of the flowers. Don't cut out the flowers, only cut the sides, keeping them joined in the middle.
You can add more details if you want to. I added some dots by popping the cardboard.
Now, join the sides using super glue as shown in the picture.
Step 4: Base, Top and Paint
Cut out 3 arch shaped pieces (1 for the top and 2 for the base) out of cardboard and make sure to measure the size before cutting. Glue 2 arch shaped cardboard pieces together and glue the other one on top of the shade. (2 arch shaped pieces that are glued together is the base).
Now, cut out a long strip of cardboard and glue it around the base (see picture).
You can design the top as well.
I also painted the flowers with golden glitter paint.
