it's been several (!) years, but hope this helps: using 3 wire hangers, insert into each other until you get a basic 'tree' formation (make take a bit). Secure with tape. Wrap the garland & lights, if desired, around the wire frame. Can't remember how I secured the garland....with wire ties from bread bags, maybe. Sorry this isn't any better....maybe it'll help a "little" bit!

It kinda sounds like ones I've seen made from tomato cages and garland and lights. I'll try to find some ideas.

I think this are the directions your looking for
