Actually, I think this project may have cost less than $5. I used those felt squares you can buy at the craft store for about 25 cents each. I can’t remember exactly how many I used but your cost will depend on how big your table is. Cut the felt into leaf shaped pieces. You can get 3 or 4 leaves out of each felt piece. Use a variety of colors. I used light and dark grey and blue. Move them around and arrange them until you are satisfied and then hot glue them together.
You could do lots of variations using different colors or shapes and considering it’s so cheap to make you could try making a few!
