Janet,
Even though my shop is on break, I look at others as a buyer (love to support my fellow Etsians.
As a buyer, I think you need to work on your pictures. Better backgrounds and a different perspective might help. Try getting lower and different angles. A tripod can really help and you can find them cheap at thrift stores or garage sales.
It looks like to resolution is too low, so you don't have sharp details. Also the lighting may contribute to that. Again, a tripod can help-eliminates the shakiness of our hands.
A really great book for learning to get better pictures is: A Crafters Guide to Taking Great Photos.
Also, I would include more product details-size, material, what makes it special. For instance, for your neck chiller, describe what's in it, why is it a neck chiller, how do you use it, the length and width, etc. Maybe show it on a model.
An avitar would help make your shop look more legitimate and appealing.
I'm not sure more items help, if they aren't the things people will buy or if you don't have good pictures. For me, bad or blurry pictures are a sale killer. I always see people saying that you need a lot of items, but I hate to see people investing money without knowing if their work will sell. I would rather concentrate on a few, high quality items with dynamite pictures and descriptions than lots of stuff with blurry pictures.
Good luck, there is a learning curve and in a year you will be surprised at how much better you have gotten!
Yes, you can have sewn as well as crocheted and knitted items.
