You have to be very competitive with others who sell similar items on Etsy, and have your items show up on the first 3 pages of search. If you are, then good job, and you will keep selling as you are. I know from selling on ebay for 12 yrs. If your on the high end, you may have a really hard time selling. Your keeping your prices low and making profit, and getting customers that will come back for more. LIttle sales add up in time, and so does your customer base.
People are willing to pay more for specialty items that are hand-made by the artist. I think your prices are spot on, but I would not have any under $5, as I see you have. Your work is for sure worth more than that.
Good job! love your items.
