I've had to reinvent myself as a designer twice in the last 3 years, and expand upon what I learned 10+ years ago. Since I was joining shops with good designers already in residence, I gleaned a lot from the styles and techniques they were using that were good and tried to update myself after being out of the floral industry for awhile. I've never wired a bridal bouquet and never seen it done, that is really old school, now many people are doing hand ties, we still mostly use bouquet holders.
I used to belong to a shop that went to many design shows, my present employers don't do that so much so I rely on the internet alot. I have found so many pictures of amazing designs and that has helped me to think outside the box and improve my creativity. I am fortunate to have worked at shops that applauded creative designs and try not to inhibit designers.
Since I found this board not too long ago, I've learned things about handling flowers like hydrangea and roses, etc. plus different design techniques. The thread on this board where everyone shares their fave web sites is great, also the pictures they have posted of their own designs. The other gal I work with is very old school and is slow to change or pick up new styles so I'm not sure if you are like minded. Maybe incorporating a new thing in a small way here and there might be your style rather than hitting it full force like me.
