My grandma has a craft closet that is like shopping at Michael's so everything I needed was handy. Here is what I started with:
A styrofoam topiary
Ribbon for the "pot"
First, I glued wide ribbon around the base of topiary so that it looked kind of like a flower pot. I just glued a little as I went and then pressed it down, working my way around slowly. Then I used a thinner ribbon to make it look like the lip of the pot, as well as to cover up where I had to fold the wide ribbon to make it lay flat.
Next, I cover the rest of the exposed styrofoam in fake leaves. I did one row at a time all the way around so that it kind of had a pattern.
After that I glued on the flowers. To make them lay flat I disassembled them and cut off the extra plastic stem. Then, I glued them back on, one layer at a time. This allows you to make them stand out or lie as flat as you like.
Use as many flowers as you like! I used a few smaller coordinating flowers to fill in the gaps between big flowers and just kept gluing until it looked like I wanted it to. When my cousin saw it and said she liked it and asked my aunt where she got it, I had my validation that it looked good!
This would look good with any kind of flower for any season and was so easy to make! Because we had a lot of stuff on hand and got the rest on clearance, this only cost $2 to make! Would you put a flower topiary in your home?
