C. Ann, I found one nifty trick two years ago, and could've
kicked myself for not thinking of it earlier. String one side
of the tree first, don't go 'round and 'round, then string
the other side. When lit, you can't really tell the difference
if you have plenty of lights.

I always get marked up since
my skin is so sensitive, and that way, I don't have to keep
throwing the lights over the tree when DH doesn't want
to help.
Good luck!
P.S. of course the niftiest thing was doing my Mom's tree
last year. My dad and brother bought her one of those that
turn on a motor, and since she had broken her foot, my sister
and I did her tree for her. What an EASY way to trim a tree.
