Hi Jessica,
Read up on SEO and Relevancy, this will help people find you, along with adding more items. I joined an SEO team which helped me get a better hang of it. Make sure to fill out your about page... use key words there and in your shop announcement and item descriptions as well, that way you will show up in google searches also. For you key words maybe cowl scarf, knitted scarf, hand knitted accessories... but research SEO and Relevancy first before making changes to see whats right for your shop and target market. I am still learning myself and by no means an expert.
Good luck:)
