This topariary was made with wired ribbon roses on a styrofoam ball on a stick. The stick was covered in ribbon. I used styrofoam in just a thrift store pot. I used my Cricut to put "Love" with vinyl on the black pot.
If you could make lots of different kinds of roses to put on the styrofoam ball, crepe paper roses or wired ribbon roses. There are some great tutorials out there.
