Flower Arranging: New found hobby

After my wedding, the thing I missed the most is ..... the flowers.. learning about various types of flowers, looking through various flower arrangement. So in the end I sign up for a Flower Arrangement workshop by Celadon & Celery. They are based in New York but they had flower arrangement classes back in November in LA. I immediately signed up and a friend also joined me yay...

Here is a picture of the LA Flower market:

And pictures of some of my arrangements:

Love me some David Austin Juliet

The red flowers (the not long and slender one) is called straw flowers and it feels like straw and feels fake.. very strange!

The dahlias are yellow in the center but pink on the outsides (But it is dying after 4 days) no like!
