When it comes to saving scraps I always determine what I will actually use- size, color, print. I do a lot of appliqué so many fairly small pieces are ( usable) but if I have something- scrap , orphan blocks or whatever; that I’m sure I have no use for I give them away. There are always people who would love ( and use) what I no longer have a use for. There is a lady who lives near me who, along with her sister, belong to a church group that makes quilts for the homeless- they love it when I send a message that I have a bag or box of scraps- and are excited to receive practice quilts and blocks. I also have sent scraps to people who have requested them for different projects. I never throw them away- I always pass them on.
