Sales always drop after Christmas. November and December are the two busiest months of the year. If you thought it would be like that year round, you will be disappointed. Other holidays may generate a little more traffic than non-holidays, but nowhere near what the Christmas season brings.
Now you will have to work on improving your SEO and adding new products. Try to get it up to at least a hundred products. Read the Etsy Seller Handbook articles on how to be found in Search. It's linked to at the top of every forum page and in your Etsy Dashboard under Community & Help.
Do something every day on your store. Either add a new product or work on the SEO on your older products. That makes the search engines find your new stuff faster.
When preparing items for upcoming holidays, try to have them up two months before that holiday gets here. St. Patrick's Day, Easter, and Mother's Day are next. But try to have some items that sell year round, for no particular reason, too.
Your embroidery work is lovely. While it is slow, post some of it to Pinterest with links back to your shop. You might also work some of the other social media sites to try to drum up some of your own traffic. You can't rely on Etsy for all of it. But there is a certain way to do social media.
You can't just drop off links and nothing more. You have to post other things, too, such as pictures, quotes, memes, how to articles, etc to give people a reason to subscribe to your feed. The idea is to develop a large following, so when you do have a new item to sell, you have a ready audience to sell it to. But if all you do is drop off links, and try to sell stuff to them, people will quickly unsubscribe from your feed. You have to offer them something more worth visiting your feed again.
