Wow, I am impressed by your number of FB fans! And I like how much variety your shop offers :)
If you are up for making new products, maybe some spring and summer themed garlands would attract customers. Many of the garlands you have labeled as 'wedding' look like fall and winter to me.
I am by no means an expert, but your titles could use a little more tweaking. Your tags are good. You are tagging phrases which is ideal. Try to fit as many of those tags into your title to increase your chances of being found.

<--- something like that...
The apples are lovely, but I kept looking through your photos to see if you had one with the garland spread out, draped over something like it would be in a wedding of a house. A photo like that would be enticing to me, because I could then imagine what I'd do with it even more. This general idea:
