Great pics...and nice to see the good, old lead/tin tinsel!! Much better than the c**P they sell nowadays.
Actually, my Mom would take it down carefully every year so we could use it again. I remember getting hollered at if I messed it up. Best to keep it off your tracks!! Those were the days!
Ah, yes, we were also a "tinsel" family, and each year, we would open up the rolled-up newspaper pages that protected last year's tinsel. which had been removed piece by piece from the tree and aligned on the newsprint before being rolled up and saved for next year's tree. Some tinsel was always lost in the process, so each year we usually had a box or two of new tinsel to make up for the shortfall (especially if the new tree was bigger than the year before!).
So, the salvaged tinsel ranged from the oldest, mostly very heavy, very flexible (but probably toxic!) lead tinsel, up to the much lighter mylar plastic version. Most of it worked pretty well, and the trimming techniques varied with the type. My favorite was the lead tinsel, since you could hold a strand at one end, and whip the other across the target branch -- the tinsel was heavy enough to lock itself around the branch and hang its full length, while "lesser" tinsel needed to be supported more in the middle. About the only truly awful version was a crinkly and springy aluminum type we bought one year that was too light and too springy to drape in any realistic fashion. Needless to say, not much of that type got salvaged and saved!
Oh, and since we never placed our tree on my childhood layout (which was permanently mounted on a foot or foot and a half high platform), I never had to worry about tinsel shorting out the tracks!
