Jemima, I'd suggest that you do some research on other shops carrying items similar to yours. You are in a VERY popular area. Today on Etsy there are for sale:
9,000 hair ties
75,000 barrettes
330,000 headbands
Some shops have hundreds of items...so to make yours get attention, you will need to create an original product twist, and then promote outside of Etsy....on FB, Pinterest, Wanelo, etc...or on blogs (maybe do a product giveaway).
If you can connect with some blogs, you have a great story to tell, since you are so young...publicity would send traffic to your shop. Meanwhile, work on your descriptions: what size are your products, made of what materials, who are they for, what makes them special!
