OK I have a question then. I have done all the above methods but one thing still plagues me. When I take a color strip (say the red or blue wing sweeps in this picture) I tape it in place but when I apply heat from my iron on long strips it wants to move. In some cases the ¼” overlap barely covers at the end. Is there any technique that I am missing?

Another question to one of the above statements of placing darker colors over lighter colors, I agree but in the case of this picture with the yellow and red wing tips checkerboard. Is the yellow box’s put over the red or red over the yellow? Yellow over red in this design would be easier.

Thanks
