I used to save all my scraps and I’d cut them down into 5 different sizes. That got old (and overwhelming) fast.
I now only keep 5” squares and 2.5” strips. It keeps things manageable. The rest gets donated to the owner of my LQS, who uses what she can for a 4H group she leads, and then shares the rest with the open sew groups. Any FQs or larger that I just fall out of love with get donated to a local charity quilting group.
