SPRAY

Lightly dust the back of the stencil with Spray Adhesive as before. Let it dry, then press the stencil onto the sail.

Grab a spray can in the colour of your choice, stand back and press the button!

Because the stencil is barely adhered, it's best to spray as close as possible at right angles to the work.

I've found that multiple light dusting coats of paint work best, build up until you get a decent coat.
