it always depends on what type of quilting you do...and personal preference. i keep everything, but i applique so use little bits. if you do not have interest in scrap quilts, or do applique or use your scraps there are always plenty of people to pass them on to. I was overwhelmed with scraps for awhile (like 5 garbage bags full) and i started sharing them...now i am not so overwhelmed with them and can put what i have to use. some people save all of their salvages, some little triangles...there are a few here doing postage stamp quilts...keep what you can use, pass on the rest :)
