To me, a throwaway is anything too small to cut with one of my Accuquilt dies. - unless it is long enough and wide wnough to be considered a string - at least 1-1/2 inches wide and 6 or more inches long.

I save my scraps for my DGD - let her decide what's a scrap.

I keep them all also..lol is that the right answer???

I keep them all. I bought two mesh laundry hampers, one black, one white. I toss the larger pieces into one, and the smaller ones into the other. I have made four baby quilts, three doll quilts, a large king size quilt, hundreds of "mug rug" for hostess gifts, and just gifts in general. I also make a varity of 9 patches to later use in
small or medium quilts.
I even have my quilting friends save their scraps for me.
I have fun with scrappy fabrics, and less gets put in the land fill. I can't toss out fabric, unless it's truly too small.
So, save those scraps. GiGi

I now only keep scraps that I can cut into 3" strips. I am collecting them with the intent of making service quilts like the 1600, except using 3" strips. I can cut them later if I need thinner strips. I cut all scraps as I go, so I have a great scrappy collection going on. Works for me.

As long as you can cut a 2" square, or a 2" strip, it's is a scrap. I started cutting 7" blocks, all the way to 2' and put them in plastic bags, label them and then do scrappy quilts when I have enough of them.

These are some crumb blocks that I made with crumbs and scraps that some members of this forum sent to me. I love them!! They are 6 inch square.

I keep everything until I have a chance to cut up squares. Anything bigger than 2x2 can be used. I cut up my scraps and then put squares or strips of the same size into Ziploc bags, label them and save them for future projects. this way they are neat and take up very little space.

I put everything I can't use (odds and ends) no matter what size...
in a bag and then give them to people that can use them, strips go to another person and the selvages to another...I just don't have the time to play with that stuff....

Love your quilt use to do things like that is a small scale for pillows etc...
