Someone on another site suggested i use pre-printed fusible to use up my scraps. But i am confused. How do you use it? Do I ever sew or just iron? I included her message so you know what she is talking about.

You know that preprinted fusible they have at the quilt stores... the one with the 1" squares all over it? Well, using that as your bottom piece, (I'd make these into small blocks... 6" maybe) use as they are, or cut all your little fabric squares just a bit larger than 1" all around, lay out onto each square, and when your 6" square is all full, gently lay a sheet of waxed paper, freezer paper or a teflon applique sheet, over the top and press. This will fuse all those little pieces to the interfacing. Then free-motion quilt all over it to hold them into place. Voila! you have a pre-quilted square.

Have no idea, but sounds interesting!

That's the same gridded fusible used in landscape quilts. With them, you iron on squares, then sew seams 1/4" in from lines on grid. If you were making a wall hanging, or something not subject to washing/drying, her method would work, but I'm not sure I'd trust it for a bed quilt.

Sounds like they are talking about Quilt Fuse.
If you Google Quilt Fuse, you will see that it show directions as to how to use it.
I wouldn't just iron stuff on to a fusable web and then quilt it. In order for it to last, it needs the raw edges done and not exposed. I don't think if you did it the way she is talking, it would make a pretty quilt. Just my opinion
