Why did you choose to practice stencil on paper, when collage is not such a durable technique?
The first reason is technical: my stencils have 5 layers (4 grey and 1 black), and to make them directly on the wall I would have to be able to dry the layers one after the other, which would require a lot of space and time. Working on very thin paper, which fits into the wall, adapting to all infructuosities, makes my work almost as durable, and some pieces have not moved for 5 or 6 years. I use paper tablecloths for this purpose, following a advice given to me by Jef Aerosol. Over time, the paper will take on a texture that I like, tearing itself off in small pieces, before disappearing with panache, gradually transforming the work.
More practically, it gives me the possibility to come in a backpack without carrying all my equipment, which would be too complicated. In some areas I couldn’t work because it would take me an hour to superimpose the different layers, not to mention the wind that could make the stencils fly away, and the lack of space to dry the matrices.
