I will do decals for restoring desktop scaled aircraft model

The design is delivered on a JPG file in a max size of letter sheet, with the content scaled, you just have to print and apply to the model or piece.

I recommend printing with a laser printer on sheets of water decals. For the application of these, read the instructions of the purchased product (water decal sheets).

Commercial aircraft models in scales 1-130, 1-144, 1-200, 1-400, 1-500, 1-600 are ideal for decals.

Consider the following.

Waterdecals sheets are normally available in a white background and a transparent background.

If the piece where you will apply the decal is painted in a color other than white, you should use decals printed on paper with a white background.
