Maybe you could start a literal scrap book of sorts, something to keep those last little bits that you can't say bye too?
(Now that may sound silly to some but I never claimed to be "normal". LOL)
I do have a little ziploc with a few fabrics that I wish I could find to get more of. None of them have any selvage info, some were given to me, one piece came from a scrap bin somewhere. I take them with me to shows, when I travel to other QS and ask around. They are older so I'm sure discontinued.
