gran, just get a good size tree branch, not a palm tree. Strip off the leaves, spray paint it white and stick it in some dirt in a planter. Then hang a few ornaments of all one color... all red or since you have lots of blue, try blue. Light it from the floor, or depending on the size from a table, with an uplight that you can use for other things like an indoor palm or ficus later on. I did that one year for a guest bedroom and it was really very pretty.
Oh I've done similar things with tree branches too. They are pretty..but if I'm in the new house this year I may get a tree with all the lights on it, or a real one and just put lights on. No one will see it but us anyway..lol. My trees are all lit all the time anyway, all year. I use the uplights and the tree lights on all of them.
I looooooooooooove lights..lol.
(and they look so much prettier at night, don't you think?);)
