Start with yard trimmings for the base. I used Azalea greenery and variegated Liriope blades and flowers. (You can buy greenery but I'm thrifty.)
Cut the Alstroemeria an inch or so longer than the greenery and distribute throughout the greenery. Cut the green mums two inches shorter than the azaleas and do the same thing. You now have a grid that serves as a solid base for the remainder of your blooms.
Add the flowers in different heights from the center working towards the outside. Alternate textures, colors and heights. The result is a great, low-cost, DIY mixed arrangement.
I typically make 3-sided arrangements and place a ribbon around the neck of the vase to designate the front.
Voila! Easy peasy.
Have a great week!
