fail experiments

when I was thinking of making a painting work,I wanted to be different with ordinary painting, so I tried to make some texture, so I spend a whole day to make the plaster dissolve to water, which become a kind of very wet white mud, I paste it on watercolor paper, wanted to make some regular texture...but I failed.It's so hard to control the shape,I can only make the paper out of flatness...and the fail work is below.
