Dina, do you have your items under vintage or handmade? If you have them listed as vintage, this may be part of the problem. Your items are upcycled which is equally as desirable and should be listed as handmade. You may be drawing the wrong audience. Only unchanged items over 20 years old are considered vintage. Those who shop for vintage may not be looking for upcycled items.
Also, look at the SEO team, you can get your items much higher in search.
Check out this team:

Give a about an hour and try to search for it and see if it helps.
Of course, there are lots of people out there better at SEO at me, and I am sure they can find even better keywords and phrases.
