I love to work with chipboards and frames from Wycinanka are just lovely!
Painting with gesso 1 -2 times, letting dry.
Painting with gesso again, put some extra layer there.
Don't wait , use your favorite mist.
After 10-15 min. you will see some nice textures.
Now it's time for some gel medium.
Add glass filler on the spots with gel medium.
Let it dry.You can also use hair spray.
Now you can use your pretty chipboard on any projects you are busy with, I added mine to the new canvas, a gift for my girl..
