I have experience in reconstructing my feelings through creating collage. One was done to express my impression to Hong Kong for a style magazine, another one was done to express my spatial conception living in a city like Hong Kong for a design publication.
Collages are wonderful because anyone can use photos/images and create something personal with them. First-timers might be worried about achieving the skills of making the collages, however, if one can take this art making process as a way of exploring his/her inner-self, emotions or memories, one would find it is pleasurable. Don't worry about the result, just enjoy the process!
