I found these amazing creations on Pinterest the other day. They are the work of Donna Rhae Marder who only uses stitches to create them primarily out of paper.
You can read more about her work here. I haven’t been able to find a web site for her, although she does have a LinkedIn profile, and her work seems to be featured in a range of industry magazines.
The creativity of people never ceases to amaze me! Go take a look.
