Well, I guess the cheapskate voice inside me is saying "Why would I pay $10 for your PDF when I can just copy the quote and design and print it myself?" I'm not saying I would, just playing devils advocate.
Also, I bought several quote items for Christmas gifts on Etsy but they were all usable items: a bracelet, a shelf, a sticker.
I think if you are going to start printing, you need to print on actual items, not just framed quotes.
If you do decide to stick with just the PDF's then you need to use every photo slot and show how the quote can be used. This item is an example. As is, it is pretty forgetable.
