Lay out some old newspaper over your work surface, to catch any paint splatters
Tape off the flags at the back of your toms.
Tape off the toms logo
Tape off which parts you don't want to be painted, such as the sole, and certain parts of the shoes.
When you are done, remove the masking tape BEFORE the paint dries, or else you might damage the paint while taking it off later.
And your done!
