Step 1: Hopefully your lights survived. I used those, ornament hangers, tacky removable poster stuff and an occasional nail
gather the objects, I found the ornament hangers above to be ideal
Step 2: Pick a location
Accept you will need to use at least one nail to build from. Estimate size you hope for and center the nail
Step 3: The star
My star had a hole I could directly insert nail into. I started all my lights from behind it and used it to hide the starting point.
Step 4: Pencil in or visualize tree outline.
At each outline point give yourself a hook. Because the weight of the lights to make the size if my tree I put a nail thru the hike in the hook and putty being part of the hook to push it forward so lights didn't touch wall
Step 5: Tree outline
doesn't need to be perfect, it will be filled in
Step 6: Make rows
make rows for Christmas tree fullness. any place cord is two long before lights start I used twist ties to shorten. you can color to match cord if choose.
Step 7: Start doing diagnals
Think of these as the actual tree lights. Be sure to hit the lights so you can draw Diana's from the various outline . the clips I used allowed the outline on the bottom of the hook and the criss cross in a higher hoop.
Step 8: After tree done, pick a spot to draw lights out toward an outlet.
Pull it out do it doesn't mess up your tree line then plug in. Be relieved that you once again have a tree to put presents under
