I enjoy putting these flowers on lapels, purses, draperies Lamp shades, waist belts, scarves or anything that could use a little pick-me up.  I even think that the clip-ons in the right size (special order but same price) might work on shoes.  Haven't tried it yet though. 
 
I apologize for the photography.  Both Pictures are of the same flower.  It is a greyed dark blue.  405-6,7, &8 are all the same color but I couldn't seem to capture it.  It is somewhere between the 2 pctures shown.
