I took a quick look at your store (via my iPhone) to see if I can spot a reason for your slow sales. Number 1–Your patterns are too small to be easily seen on product thumbnails, so try using a larger scale with patterns to see if that helps you generate sales. Number 2–On your Christmas products, your cover photo backgrounds are competing with your designs, making it difficult to see and focus on your holiday products. Try using more subtle colors and more simple background graphics so your products are the star of your cover photos. If your cover photo backgrounds have more than 2-3 supporting objects, they are too busy.
Most people shop on Zazzle using their iPhones, so your thumbnails need to be easily viewed on mobile devices. Always keep this in mind moving forward.
Hope this helps and that you make some holiday sales!
