In my opinion its your tags they are very generic so they are going to show up in a search that has a lot of items like Accessories has 1,981,274 items and Children has 1,420,733 items
i would rewrite them to be more what you would search for when looking for the item. this post helped me a lot after i read it i have reworked my tags and shop and got more hits on items (sales are still slow im new)
http://etsymentors.blogspot.com/p/critique-your-own-shop.html The other thing i notice you have let me know which one you want i would list each one as its own listing so like the pink one would be its own listing like this
http://www.etsy.com/listing/99057117/black-soft-kanzashi-headband-sz-6-18This listing for me would be for the size 6 to 18 headband with the black white and green flower.and talk about the size like how big around it is. then i would do your next size up or down with the same flower just different size (double your listings not your work) if these flowers are not one of a kind if that makes any sence
you have a great shop i love your items
