Yes. I like it shoved into the middle of the tree so it doesn't look very tinselly but creates a lush, glowy effect. We have multi-coloured lights because DS has surprisingly strong views on white ones.
DH tried to do a matchy matchy tree last year, using only about a quarter of our bauble stash. As soon as he went out I got the rest of the decs from the loft and shoved everything on the tree - random baubles, old homemade crap, weird clip-on glittery butterflies that DS had chosen when he was a toddler - the lot. It looked like Woolworths had thrown up on it and truly was a thing of beauty.
