Right now I'm still thinking that dye is my best bet.

Things You'll Need:

• Old Nylon Stockings
• Flowers
• Cookie Sheets
• Stockpots
• Cookie sheets

1. Step 1

   Dry the flowers of your choice in a single layer on a cookie sheet at 150 degrees F.

2. Step 2

   Put the blossoms in a nylon stocking and tie the top shut.

3. Step 3

   Cover the flowers with cold water in a stockpot.

4. Step 4

   Bring the water to a low boil for about ½ hour.

5. Step 5

   Remove the pot from the heat when the water is the color you want it to be.

6. Step 6

   Remove the stocking full of flowers.

Tips & Warnings

• Some flowers, such as dandelions, lose their color when dried and should be processed fresh instead of dried.
• Dandelion plants produce a nice magenta color; the roots will make purple.
