Do you keep all of your fusible, poly, cotton, etc. scraps and keep them sorted as you do your fabric? Or if you keep them
do you just put them all in one container and sort as needed?

I'm not to neat with any of my supplies. I do keep the batting together. I use the small pieces a lot. I don't toss them!

As I've limited space in the study room where I sew, my battings are all stacked up in boxes. I do hope I could be more organised but currently, this is the best I could do.

I keep all my batting pieces together. And I try to keep my fabric scraps somewhat sorted by size. I also try to keep the scraps sorted by type- batik, 30's, civil war, christmas etc. I use alot of ziplock gallon and two gallon bags and then throw into big containers.

All my battting pieces are together (in my sewing room closet) with larger pieces hung over pant hangers with the cardboard rolls. I try to pin a note to each with the size of the piece.

I keep mine separated in bags, but store all in one big bag.

Me too, except I use a large tote for all the smaller bags.

I have a seperate bucket for batting trimmings. I save everything that is more than about 1 1/2 inch wide. its amazing how fast an how much can get accumulated. I use small trimmings pieced together in potholders.
Larger pieces more than 10 inches wide get folded and in its own bin.

Save my batting also.

I keep batting scraps in one bag, flannel in a small box, fleece in another bag, and regular quilting cottons sorted by color in smaller bags inside a larger bag. I currently have all the blues & whites in a separate bag with log cabin foundations for a WIP that I work on when I feel like sewing but don't want to think too much. I just have to remember blue or white and sew on the line.
