Also, don't be too stingy with the overlap- at least 1/4 inch-  and put the lighter color under the darker color.  

 You can also do it by putting a complete base color down and then adding the trim on top of it.  Best done with a "cold technique"  - ie, take the backing of the monokote off and lay it down on a layer of windex or slightly soapy water; then squeegee out all the liquid and let dry. This will result in way fewer bubbles than any "hot" technique that I know of.

I only did it once on a Midwest extra 300 wing. I joined the straight-line
color changes across the open rib bays before shrinking being careful to
only heat the overlap. Shrinking with a heat gun will cause the seams to
slip unless shielded from the heat. It held up well until a mid-air required
patching a rather large portion of one wing panel. Mating un-shrunk covering
to previously shrunk covering caused some wrinkling where the colors joined.
I have avoided trim schemes requiring color changes over open structures
since that were too large to add a second color layer over a base. Once was
enough.

This question is not about pattern planes but I know one of you guys out
there has the answer.  When covering a built up wing (ribs and spars) with
Monokote, how do you change colors over an open area?  Do you tack the whole
pattern together and then apply it as one sheet?  Or can you iron pieces
together on the wing even though there is no balsa to back it up?
