I have made 16 mini trees (regular incans wrapped...) for my first year (last year). I held the top together using small hose clamps. A little knuckle dragging solution, but it worked pretty well. I tried ty wraps, but I found that they "slip off" of the top of the tree, so I went to the ty wraps. I just read last night on the spring planet Christmas magazine that they use washers--slip them over the three ends and it kinda locks them in place. Some ideas for ya...
