I would change titles and tags. I noticed most of your towels have same tags and your hand towels start with "Embroideried hand towel…" You want to give titles and tags variation. Also, there are some good words you used for tags but didn't include in the titles.
Another thing I noticed is comma in the title. I am not sure Etsy works the same way as Google, but you need to have space AFTER the comma to show up in correct search. Some of your titles don't have space or have space before comma but not after.
The last thing I noticed is the pictures. I would omit all the decoration from pictures. For example, this listing:
