I wanted my wreath to be all white and cream-colored. My frame was a bit yellow, so I added white paint to the edges. You can leave your base a natural color or spray paint it to match your decor. 

Use two styrofoam ball halves or cut a ball in half.

Hot glue the two halves of the ball onto the lower left corner of your wreath. 

Add craft wire around the balls to secure them. 

Cover the styrofoam balls with Spanish moss using hot glue.

Spray paint your twigs white. 

Insert a few pussy willow branches and a branch or two of the bleached oak leaves (or branches of your choice) along with the spray-painted white branches. Insert them into the styrofoam going up along the edge of your frame. 

Insert a few horizontal branches along the bottom edge of your frame. 

You can use any paint color to dye your flowers. Add a small amount of acrylic craft paint into a paper or plastic cup and add a little bit of water. 

Dip an individual sola flower into the paint mixture and swirl it around to get a good coat on the flower. 

I chose to use white paint because I wanted all white and cream flowers. 

Remove the flower and blot any excess onto a paper towel. 

Allow to dry. 

If your flowers did not come on a stick, you can add floral stem wires to the base of the flower so you can work with them. 

I gathered a few fall leaves from the yard and spray-painted them with a light coat of white paint. 

Hot glue them into the wreath where you would like them. 

Start inserting the flowers into the wreath where you want to place them. 

I hot glued a 6" wood skewer to some flowers and cut it to approximately 3" long. This way, it is easy to insert them into the styrofoam. 

I also directly glued some of the flower heads without a skewer. 

Attaching the wood flowers at different heights gives the wreath dimension.
