Summarize this article in one sentence.
If you want a classic hydrangea color, go for light blue, lavender, pale green, or pink. You could also select some green tissue paper if you want to make leaves. Cut your wire pieces at 6 to 8 in (15 to 20 cm) and bundle them together neatly. Wrap the bundle with floral tape about 2 in (5.1 cm) from the top of the wire. With hydrangeas, you shouldn’t separate the petals too much, but try to separate the petals a bit and move the ends around after the glue has dried. This will make the flower appear fuller and more natural.

Summary:
Choose several sheets of colored tissue paper for your flower. Cut and bundle 30 pieces of floral wire to make the flower’s base. Fluff up the petals.
