Here are some Decoupage tips to get you started.
These days, there are lot of pretty papers available. Just visit any craft store and you are spoilt for choice. Choose those paper with individual motifs or motifs that are clustered together. These paper are also called pattern paper which are used for scrapbooking. Choose those that are not too thick. You can also use gift wrapping paper, images from magazine, images from books, postcards. For surfaces that are thick like postcards, you can thin the layer by peeling the extra layers away gently. I also found a lot of pretty servittes in our local department store. These servittes can be used for decoupage too. Just peel off layers of tissue away,remaining the top pattern layer.
To achieve a smooth surface, we need to varnish about 10 to 12 coats of varnish. Between each coat, let dry for about 1 to 2 hours. Use a hair dryer if you are in a hurry. For a more professional finish, lightly sand back the penultimate coat with fine grade sandpaper until you have a smooth finish.
For those who like a vintage look (which is the current trend) apply a layer of antique medium over the second coat of varnish. It is at this stage that you can still see the texture of the buish marks in the paint, and it is these that help to give the surface finish depth. There is also an added advantage if you realised that you have applied too much antiquing medium, you can wipe it off with a soft cloth. You can also make your own antiquing medium by mixing acrylic paint Raw Umber with water. Brush over the project with a sponge brush or bigger flat brush. Wipe off the excess paint after a minute or two rubbing the colour to the edges. To create a softer look, I usually use a paper tower to rub onto the project.
