open a window or do it out side.
or don't, you won't lose many brain cells just doing it a few times.
play around with it a bit, do it on spare pieces of paper before putting it on anything important.
It takes a little bit of practice to figure out the best distance and intensity to use the spray can for each stencil to get the best print.
also spray mount is a stenciler's best friend. Its glue in a can. Spray it on the back of your stencil to make it stick to whatever, it will stay sticky, that way you don't get so much off spray.
2 am seams to be the best time to go out, for me anyways.
if a cop drives by DON'T FUCKING RUN!!!!!!!!!!!!!!!!!!!!!!!
Then they know your doing something wrong and if you do run they will
catch you. Just slowly stop what your doing, and walk away. If your doing this in a major city cops aren't going to take much notice, in the suburbs they'll care. Owners of buildings will also care. Random people walking by normally don't care.
But anyways rock the fuck on, i haven't found anything more fun than walking around putting my stencils places.
