Dryer Lint

What do you do with your Dryer Lint?
My fascination with Dryer Lint began about a year ago when I moved into a house after living in an apartment in Brooklyn, NY.
My Mom was over and she was very insistent about making sure I clean out the dryer lint, because it can start fires!!! Ahhhhhh...there are so many things a 1st time house owner needs to know...
