Step one – Apply gesso with a palette knife so that some areas are thicker than others.
Step two – heat with embossing heat tool/paint stripper gun on low setting. Keep moving the heat around the piece until the gesso starts to form a skin on top and blister up.

Step four – paint!
step five – you can add another colour of paint over the top, and wipe some away to highlight the texture. rub’n'buff will also highlight the texture beautifully.
