I LOVE tinsel. Draped all over the place. 
I think a Christmas tree without tinsel looks 'unfinished' and bland... I much prefer the old traditional style of decorating a Christmas tree, (well 1960s, 1970s, and 1980s,) to the 'modern' way of doing it. The modern way features pretty much just baubles, and maybe a few lights (and they're pretty much always white.)
Pic 1 is how I like to see a Christmas tree! Pic 2 is how many seem to look these days. (I'm not a fan of the way they often look now!) Give me lots of different decorations - bits of holly, red ribbons, snowflakes, little robins, stars, fairies, gingerbread men, coloured baubles, gold bells, silver bells, and all manner of tree decorations - as well as lashings of tinsel, and pickwick lights!
