Sketching

My friend Penny came over on Friday so I could show her my technique for doing collage. As she started making a "sketch" using color aid papers and fabric to be a study for an art quilt, I began gluing down leftover shredded paper to work on a few ideas.
I see with the top one that making a landscape with random pieces could easily happen... weaving or using vertical strips has possibilities... and abstract scenes can work, too. What feelings are evoked for you when you look at these sketches?
