Make the things you'd like to sell. Make them often, and make sure they excite you. Put them out into the world. Tell people about them! I find myself sharing these words with students often....I wish someone had told me these things when I was starting out! 
Floral design is an art form, and we are artists! Each pair of hands has the ability to create unique, expressive work. How exciting is that?!
