I finally got around to trying to figure how EXACTLY how to wrap my arches. I have Wal-Mart 100ct mini's and when fully wrapped one layer thick, they take up 16" on my 10' 3/4 Schedule 40 Grey Conduit. This is too much as I will never get the others to fit.
I did this quite tight so that the wraps do not move. It seems like I am going to have to make about 10 double layer passes to get the lights to fit in a 12" span. Does this sound right? Do you wrap your lights tight?
