Does anybody know how to make a practical airbrushing mask for creating nice soft edges? I must admit I build solid-color tanks only because I'm afraid of camo patterns with soft edges-I had extreme problems with creating soft edge camo in the past. My Badger Anthem just wasn't up to it and I suspect it requires some unbelievably precise airbrush spraying very thin, sharp edges to attempt it freehand.
In the past I tried shooting through an index card with an irregular hole punched in it. You attempt to create a soft edge by holding the card a few milimeters away from the model but the whole thing only increased my frustration. The card flaps back and forth in the strong air stream and, to make it worse, it covers the area being airbrushed making you blind because you can't see the pattern as it appears under the card. You're forced to stop constantly to check the progress underneath the card.
I just ordered a roll of Parafilm and will experiment with it but this type of masking foil is for creating sharp camo edges and this is not what I'm looking for really.
