Suggestions, Opinions, Criticism...Please

So the Mason Jar craze is still going strong, and as a crafter it's getting harder and harder to keep this trend in my shop fresh an unique. I have come up with something I like and enjoy creating, but I would love as much feedback as I can....from all of you!  So give it to me...honest opinions, suggestions to make them better, ways to make these creations a MUST HAVE!
