What lovely items! I think a good next step might be to reshoot your photos in a more cohesive way. Check your stats and see which listings are getting the most attention, and try to shoot all your products in the same set up, so that your shop has an overall visual theme. Personally, I thought this one was the strongest:
http://www.etsy.com/listing/125677775/acrylic-citrine-water-hair-sticks-6Bright background, pretty and simple prop, and really makes the hair stick stand out. The ones on a dark background are harder to fit into treasuries because the backgrounds don't jive as well. I also liked the hairsticks on models, so perhaps you want to shoot them all in use? Hope this helps!
