Simple, modern art made only of foil and fun.
All you need is aluminum foil and scissors. It's a great way to use old cups and foil that you don't need or was used.

Step 1: Cutting

First you should cut a piece of foil any size, so you can use any height. I chose a medium sized piece, because if you make a good amount of medium sized flowers, you can make a boquet

Step 2: Making the Petals

Next, you should cut strips of foil. Keep in mind the size and depth of the petals you want. I chose small, wide petals.

Step 3: Rolling

Roll the foil so the petals are on the outside. You will want to twist the stem so it looks proportional.

Step 4: Shaping

You may want to bend the foil so your petals actually look good, unless you accidentally rolled it so it looks good.

Step 5: Additional Inspiration

You could take an old solo cup, and put a hole in the bottom. The reason for this is you can put a phone or colored light on the bottom to reflect the light off the flower(s)
