Here is my version:
These are simple to make. I got the glass ornament at Michaels at Christmas time. I decided to etch the ornament to give it a little something extra, but you wouldn't have to. I then cut the wedding invitation into strips, rolled the strips and shoved them in the ornament.
Now I can cross this off my list of "Pinterest ideas to make". I like it so much, it might become my go-to extra little gift at the weddings I attend.
