How we made the stars and cross in lights for the Christmas Essay Play.
We used three strands of lights to show the little stars and the big star.  Two of the sets of lights were unplugged leaving the cross at the end of the play. 

A long strand of small lights was pinned at random places on the back of a large navy sheet.   It was hung on a wire and the lights shone through like stars in the night.  This was strand 1.

We used a very large piece of heavy cardboard for the 2 strands of larger lights of 25 bulbs each, which had to be hung on a rod due to the weight.  It will be easier to mark the cross first, then add the markings for the star shape.  We removed the bulbs from the wire and cut the holes just large enough to push each end through and screwed the bulbs back in.  Draw your cross as large as you want it and mark it as shown below with equal spaces between each bulb.  Start at the bottom and push the bulbs through in the numbered order.
Start here with
Strand 2 and skip
holes to work your
way up, and back down.
