Thanks for that answer that was what i needed. One more thing. My roof is a gable roof. and my view is that of the side. So as I layout my strip it bends at the peak of the "^" gable. I have two of these which run one string each. In the layout i have to make two strings. in order for me to make it act like one string I have reduced the number of nodes for the lay out to give me a combined number to match the string then grouped them. Is that the way I should do it to give me the look of a single string of lights.
Thanks,
