Rebecca - I really like your artwork! I know that cross stitching is time consuming, but I think it would be great if you had some larger sizes also.
I think you should try working on your titles. Almost all of your listings begin with "Framed". Lots of people are probably not going to search using that exact word.
You have a lot of listings, I would suggest varying the titles a little and see what works. Maybe focusing on the colors, or words like "geometric", "modern", "colorful". Most people searching probably won't know that they really want a Framed Triangle Cross Stitch until they see it. So if the title is a little more encompassing in the beginning, I think it will get more views.
Also, I could see your kitchen mixer piece being a cute housewarming gift, or a gift for newly weds, maybe try focusing on what the final use of the product will be.
Good luck! It seems like views are down for the month of April anyway, I know they have been for me!
