Ok, you have two choices.

1) you can build the color scheme off of the plane and then move it to the wing to cover. To do this you'll need a sheet of glass or a mirror to build the pieces on. You can get a full length mirror at Wal-mart for about $15. Measure out your wing area and figure out how big you need your pieces. I would start with the black center section and move out. Take your next piece and lay it on the first piece with about a 1/4" overlap with the first piece. .Use a trim iron or the tip of your covering iron to seal down the overlap area of the two pieces. Continue building your piece until you have all the pieces ironed together. Now transfer to the wing and shrink in place as you normally would.

2). Lay down a base white coat on the wing and build up the trim pieces over it. Lay each trim piece in place and then carefully iron down. Start at the bottom of the wing and hold up the loose end of the trim piece, and slowly iron it in place. Do it this way to avoid any air bubbles. If any develop pull the piece back to release the trapped air and then re-iron it. I after the entire piece is applied you still have air bubble use the tip of your X-acto knife to pop the bubble and iron it out.

Of the two methods #1 is the best, but not the easiest. This is because you have to make sure EVERYTHING is straight as you are applying the covering on the wing. But this will result in a lighter covering layer. #2 is the easiest, especially for those getting started in covering. If you don't have lots of experience I would recommend #2
