I was never a huge fan of collage as I thought it a place for people who cannot draw but liked to use scissors and glue. As time went on in art, I started experimenting with collage as a way to plane out larger pieces. I still prefer hands on materials to photoshop so I find the process therapeutic. There is something soothing about mixing images together, cutting them with scissors or a blade and gluing them in place. I do not find the same enjoyment/ therapy from photoshop and the downside of digital is there is not a true "hardcopy" (save a printout.)
I think a lot of anxiety in the world could be squelched if people would do more things with their hands. As early humans I suspect most of your day was spent doing things with your hands to keep your family alive, making baskets, sharpening tools, repairing things..etc etc. I suppose the loss of this could result in a build up of psychic energy and stress. That is why we spin fidgety things in our hands now. A good pair of scissors and a swap file. (a file of random images I have keep for 30 years) and you can get back to being a kid again who
still enjoyed art for arts sake and the act of pure creation.
If you really enjoy a piece of art, people resonate with it on a vibratory level because they have the same desire in them to express themselves. If you get really good at expressing yourself and/ or turning the sand grain in your mental oyster into
a pearl of genius someone else may even decide to pay money for that token of your anguish. I would normally throw away such studies
for "real" or finished works but I find people like to own them.I
personally am as much interested in an artist's thought process
and studies and sketches as I am the final products. I sell my studies Here.I find money to be very therapeutic and a lack of money to be the obverse.
