I like them all but not all together in one project. Most importantly if you like them that is all that matters.
As for me, I would like the first fabric for a tree skirt...the dark fabric wouldn't show dirt...but I have a live tree.
The stripe fabric may look nice as a binding, cut on the diagonal or missouri star has a tutorial on blocks using stripe fabrics. The checkered fabric makes me think of a picnic or potholders and the green fabric looks springy or for an Easter table runner. I look forward to what your vision is for your fabrics!
