Topiaries are very classic pieces, and they are not as intimidating to DIY as they look! Here are pics (courtesy of my brilliant brother) of one that I made using leftover scrap flowers from a wedding:

As promised, here are instructions to a very basic topiary:
Materials
1. Pot (here I’m using a 6″ terra cotta)
2. Plastic grocery bag
3. Disposable chopstick or sturdy and relatively straight tree branch
4. Plaster (available at your local hardware store)
5. Disposable container, stir stick, gloves, and water for mixing plaster
6. Wet floral foam
7. Floral moss
8. Floral Tape
9. Ribbon, wire, pins
2. Line pot with a plastic bag
3. Mix plaster per instructions on box
4. Pour plaster in lined pot leaving a 1.5″ to 2″ space from the rim (see brother GT hard at work here in my hot garage)

5. Place chopstick or branch in the middle, make sure it’s straight (approx. 1″ in plaster).
I also painted the chopstick brown so it’d blend in better.
6. Let plaster dry (per instructions on box, I leave it overnight to be safe)
8. Cut floral foam to fit the pot to the brim

11. Peel back moss in the middle to give room for arrangement
12. Cut flowers to desired height and stick each stem in foam surrounding the stick
13. Tape together the stems at desired height with floral tape (make sure you’re taping where the stick still reaches for max support)

14. If you want, you can make a floral bow to add to the arrangement.

15. Cover floral tape with ribbon and pin the ends

16. Arrange more flowers on the bottom and add bow as desired

Viola! (and keep the foam wet to maximize the life of the arrangement!)

AMAZING!!!!! I am totally going to use this for our chuppah supports. Thanks so much, Miss GT!
