Infinite Filament

I bought this reel of silk filament at a clearance sale, I don't know how many years ago: I've used it a lot. Mainly to ply with. This morning I used it to ply the last of my angora-merino drop-spindle yarn. As if it wasn't delicious enough already! The strange thing is the reel never seems to get any smaller. Of course I didn't weigh it when I first brought it home. It was part of a boxload of stuff and I'm sure I only paid a couple of dollars for it. It isn't really infinite and maybe if I live long enough to spin up all the fibre I have at my house I'll eventually get to the end of it. But meanwhile, there it is in its fine magenta lustre waiting to be added to one more skein
